13 Best SMS Marketing Platforms & Software, Tested (2026)

Almost no SMS platform quotes you the price you will actually pay. The number on the pricing page covers the subscription and, sometimes, the messages. It rarely covers carrier pass-through fees, which add roughly $0.003 to $0.005 per SMS in the US on top of whatever rate you were quoted, and it never covers the second and third cost layers most vendors leave off the page entirely: per-segment billing on long messages, and MMS at two to three times the SMS rate.

This guide gives you the true monthly cost for each tool, what 10DLC registration actually involves, where deliverability is held up, and an honest verdict on who each platform is wrong for. Every price was verified against live vendor pages between May and July 2026. If you want the underlying cost mechanics first, our breakdown of how SMS pricing is structured explains the three layers in detail.

This article is part of our SMS marketing guide.

SMS Marketing Platforms: The Fast Verdict

Best for	Recommended platform	Why it stands out	Platform starting price	True cost at 5K sends
Small business under 5K sends/mo	Sender	SMS steps sit inside the same automation flow as email, so you do not run a second tool	$7/mo (Standard)	~$98.1
Shopify-only ecommerce	Postscript	Reads Shopify order history, cart data, and 45+ segmentation filters in real time	$49/mo minimum	~$49 + carrier fees
Email, SMS, and push in one flow	Omnisend	Three channels in a single visual automation builder	$59/mo (Pro)	~$108.5
Lowest per-message rate	Twilio	$0.0083/SMS US with no platform fee, if you have developers	No platform fee	~$41.5 + carrier fees
Irregular or international volume	TextMagic	Pay-as-you-go with no monthly floor, credits that do not expire	$0.035/SMS PAYG	~$185
Enterprise DTC at scale	Attentive	Managed compliance with an in-house legal team, two-tap signup, RCS	Quote only	Quote only

How We Evaluated SMS Marketing Platforms

Each of the 13 SMS marketing services were compared on its entry-level paid plan against a standardized list of opted-in contacts who had engaged in the previous 30 days. Contacts were not purchased or scraped. Testing ran on a production Shopify store, and pricing was re-verified against live vendor pages between May and July 2026.

What we measured, in order:

• Automation features and depth: trigger types, conditional logic, branching, and the automated workflows each platform can build without a third-party connector
• List management and advanced segmentation
• Lead capture: keyword opt-ins, QR codes, website popups, and signup forms used to collect phone numbers
• SMS deliverability, using third-party testing data
• SMS compliance tooling: 10DLC registration, opt-out handling, opt-in consent capture, and Telephone Consumer Protection Act (TCPA) and GDPR options
• Customer support responsiveness on the entry-level plan, across chat support, email, and phone calls
• Customer reviews across G2, Capterra, Trustpilot, and Reddit
• SMS pricing model, including carrier fees and per-segment billing

Deliverability testing. We ran a 500-message send per platform to a clean list and recorded delivery rate, time to inbox, and carrier rejection codes, then cross-checked against third-party benchmarks and CTIA messaging guidelines. Every test used identical content, 10DLC long codes, and equivalent send windows.

User reviews. We gathered feedback from G2, Trustpilot, Capterra, and Reddit and analyzed recurring themes: 10DLC friction, support quality, pricing transparency, and feature reliability. To avoid cherry-picking, we looked for patterns across a large volume of recent reviews from the last 12 months and weighted positive and negative feedback equally. For Klaviyo, Attentive,, and Postscript we added structured interviews with three to four current users each.

What was not tested. MMS deliverability at scale, RCS messaging, WhatsApp beyond Sender and Omnisend, and enterprise features such as dedicated short codes, SSO, and custom SLAs. This review targets SMBs, ecommerce brands, and agencies with lists up to 500,000 contacts.

Pricing methodology. All pricing was verified between May and July 2026. Where a vendor publishes no rate card, we say so and label third-party estimates as estimates rather than presenting them as vendor pricing. Carrier fees are listed separately wherever they are billed on top of the subscription. All prices are in USD, monthly billing unless noted. Check each vendor’s pricing page directly before purchasing, because SMS tiers changed at four of these platforms during the testing window alone.

Our reviewers combine hands-on platform testing with user sentiment from Capterra, G2, Trustpilot, and Reddit. You can read the full process behind our scoring in our review methodology.

SMS Marketing Platforms: Quick Comparison

True Cost at 5K, 50K, and 500K sends/month

Every figure below is the plan fee plus the message cost at the US rate, rounded. Carrier pass-through fees are counted only where the vendor bundles them, and the final column tells you which ones those are.

Platform	Best for	5K/mo	50K/mo	500K/mo	Carrier fees included
Sender	SMBs adding SMS to existing email automation	~$98	~$909	Contact sales	Yes
Klaviyo	Shopify stores already on Klaviyo for email	~$90	~$830	Contact sales	Depends on the region
Omnisend	Email, SMS, and push in one flow	~$113	~$990	Contact sales	Yes
Attentive	Enterprise DTC above $5M revenue	Quote only	Quote only	Contact sales	Yes
Postscript	Shopify-only brands wanting an SMS specialist	~$75	~$750	~$7,500	No
SimpleTexting	Businesses wanting every feature on every plan	~$243	~$913	Contact sales	Yes
TextMagic	Low or irregular volume, international sends	~$110	~$2,450	Contact sales	Yes
SlickText	Mid-market campaigns with keywords and surveys	~$169	~$939	Contact sales	No
Textla	Very small teams wanting no wasted credits	~$75	~$525	~$5,025	Yes
Textedly	Local service businesses sending simple promos	~$169	~$1,020	Not published	Yes
EngageBay	Small teams wanting CRM, email, and SMS together	Not published	Not published	Not published	Partial
EZ Texting	Marketing teams wanting AI copy and stock imagery	$75 (500 contacts) + overage	Contact sales	Contact sales	Partial
Twilio	Developer teams building SMS into their own product	~$41.5	~$415	~$4,150	No

Notes on the numbers. Sender assumes the $7 Standard plan plus credits at roughly $0.015/SMS. Klaviyo excludes the profile-based email plan underneath it and assumes roughly $0.01/SMS with the $15/mo SMS uplift. Omnisend assumes the $59 Pro plan plus $0.007/SMS; spending bands have changed since May 2026, so confirm current tiers. Postscript figures sit on top of the $49 minimum and exclude carrier fees.

SlickText figures are credit cost only, because its $0.0042/SMS carrier pass-through is billed separately and adds roughly $21 at 5K sends and $210 at 50K. SimpleTexting figures add the $10 local number to the nearest credit tier. Twilio excludes carrier fees, which vary by carrier and cannot be stated as one figure.

13 SMS Marketing Platforms: Honest Reviews

Each review below leads with the verdict, then the evidence behind it. Choosing the right SMS marketing platform depends less on feature counts than on whether your SMS marketing campaigns are promotional broadcasts or two-way conversations, and on the volume behind them. Pricing, limitations, and the “who should look elsewhere” call get the same depth for every tool, including ours.

Sender

Sender is the cheapest way to add SMS to an email program you already run, because SMS steps live inside the same automation builder as email rather than in a separate tool.

Sender: What We Found in Testing

• 10DLC registration ran hands-off. I submitted brand information through the dashboard and carrier approval landed in 8 business days with no follow-up required.
• Multi-branch flows build natively without workarounds. Our team assembled a 5-step abandoned cart text sequence with conditional splits in under 40 minutes, the fastest of any platform in the cohort.
• Deliverability on a 500-message send to a clean list came in at 98.4%, matching the top performers we tested.
• Custom events are the feature most buyers miss. You send a named behavioral event from your site through the API, such as “Watched 50% of a Video” or “Renewed Subscription”, and that event can fire an SMS in real time or build a behavioral segment. The setup steps are documented in Sender’s guide to tracking custom events.
• The shared inbox works but stops short. You can assign conversations to team members. There is no internal commenting and no conversation tagging as of Q3 2026.

Sender Pricing

Volume	Estimated monthly cost (US)
5,000 messages	~$98
50,000 messages	~$909
500,000 messages	Contact sales

SMS is not available on the Free plan. Standard starts at $7/mo with credits purchased separately. Professional starts at $14/mo and includes free SMS credits equal to your monthly subscription fee, so a $50/mo Professional plan carries $50 in credits. US rates run roughly $0.015 to $0.02 per SMS. Carrier fees are included. No minimum monthly spend. Confirm current rates on the pricing page.

Compliance

10DLC is fully managed. Opt-out processing is automatic and handled within the send, so STOP replies are honored on the same message. Double opt-in is configurable but off by default, which means you have to enable it. GDPR tooling covers consent logs and data deletion. EU data residency is available but requires a support request rather than a settings toggle.

Who It’s For and Who Should Look Elsewhere

Sender fits ecommerce and SaaS teams under roughly $2M ARR who already run email here and want SMS in the same automation builder without a second subscription. It does not fit SMS-only marketers, brands that need product-level Shopify revenue attribution, high-volume promotional texters, or anyone sending outside Sender’s supported countries.

The One Thing Their Marketing Won’t Tell You

There is no dedicated short code option, so sending runs on long codes and toll-free numbers, and MMS is not listed as available. If image-heavy campaigns or a short code are part of your plan, Postscript and Attentive are the honest answer.

---

Klaviyo

Klaviyo is the right SMS platform if your email already runs on Klaviyo, because the predictive analytics powering email segmentation power targeted messaging too. Its cost curve is the steepest here, and its 22-country SMS footprint rules out most non-US programs.

Klaviyo: What We Found in Testing

I evaluated Klaviyo’s SMS on a Shopify Plus store with 22,000 contacts, and our three user interviews surfaced consistent patterns.

• On 13 July 2026 Klaviyo moved new accounts and Free-plan accounts from credits to dollar-based mobile-message pricing. Existing paid accounts may still bill on credits, so what you read in older comparisons no longer describes what you will be quoted.
• All three interviewees started on Klaviyo below $1M ARR and were satisfied with the value. Two of three were considering migration above $2M ARR on cost. One with 26,000 active profiles sending 40,000 texts a month described SMS at roughly $2,150/month as hard to justify against email performance.
• Support responsiveness dropped from same-day at lower tiers to two or three days at higher tiers, in their words.
• SMS, MMS, push, and RCS sit as steps inside the same flows as email, so abandoned cart SMS, post-purchase, and win-back sequences, the customer retention flows most stores run, all support text without a second builder.
• Two-way SMS is native. Subscribers reply, replies trigger automated responses or route to support.

Klaviyo Pricing

Volume	Estimated monthly SMS cost
5K sends/mo	~$90
50K sends/mo	~$830
500K sends/mo	Contact sales

Figures sit on top of your profile-based email plan, not instead of it. The Email plus SMS plan runs roughly $15/mo more than Email-only at each tier. US SMS runs near $0.01 at high volume and higher at low volume. MMS costs roughly 3x SMS. UK rates run about 5x US. The Free plan includes $5 in mobile messages, changed from 150 credits on 13 July 2026. There is no annual SMS discount. Confirm at klaviyo.com/pricing.

Compliance

Assisted 10DLC with observed timelines of 7 to 14 days. GDPR tooling is thorough. There is no dedicated HIPAA path. TCPA double opt-in is configurable rather than enforced.

Who It’s For and Who Should Look Elsewhere

Klaviyo suits ecommerce brands already invested in its email ecosystem that want unified attribution across both channels. It does not suit stores outside the 22 supported SMS countries, brands sensitive to cost at scale, teams with large low-engagement lists (active-profile billing charges you for every reachable profile whether you text them or not), or anyone who needs predictable volume-based pricing.

The One Thing Their Marketing Won’t Tell You

Getting out is harder than getting in. Segment logic, flow conditions, and custom properties do not export cleanly, so a complex Klaviyo program is effectively a Klaviyo-shaped program. Budget around 60 hours of rebuild time, and read our notes on moving a Klaviyo setup across before you commit to a date.

---

Omnisend

Omnisend runs email, SMS, and web push through one automation builder, which is the reason to pick it. Since 4 May 2026 SMS is locked to the Pro plan for new customers, so the entry price for text is $59/mo, not $16.

Omnisend: What We Found in Testing

I evaluated Omnisend’s SMS on a Shopify store over three months.

• The unified builder held up. Building a sequence that sends an email, waits 24 hours, then sends an SMS if there was no click, with a separate branch for purchasers, took 22 minutes and needed no documentation.
• Shopify integration is strong but not Postscript-deep. Product-specific triggers such as back-in-stock on a named variant fired reliably. Cross-sell triggers keyed to purchase history took more configuration than expected.
• The AI segment builder creates SMS audiences from plain-language prompts, which shortened list-building for one-off promotions considerably.
• Legacy accounts are a real variable. Customers who signed up before May 2026 may keep older SMS access or included credits, so two Omnisend users can describe completely different pricing and both be right.
• Support is email and chat only, with a median response of one hour in our testing. During a live send failure, that is a meaningful gap.

Omnisend Pricing

Volume	Estimated monthly cost
5K sends/mo	~$113
50K sends/mo	~$990
500K sends/mo	Contact sales

SMS requires the Pro plan at $59/mo minimum for new customers since 4 May 2026. Credits are bought as an add-on, with entry rates starting near $0.007/SMS. The Standard plan at $16/mo has no SMS capability for new customers. MMS is available for US and Canada recipients only, at higher rates. Spending bands have changed since May 2026, so verify current tiers in Omnisend’s support documentation.

Compliance

10DLC registration is assisted, meaning guided self-submission rather than a hands-off process. Opt-out handling is automatic. TCPA double opt-in is optional and must be switched on. EU data residency is available with a documented GDPR program. No HIPAA documentation exists, so it is unsuitable for healthcare.

Who It’s For and Who Should Look Elsewhere

Omnisend fits Shopify and BigCommerce stores on the Pro plan that want three channels in one flow, particularly teams already running ecommerce email campaigns there. It does not fit anyone on the Standard plan, SMS-only senders paying for an email engine they will not use, brands chasing the lowest per-message rate, or teams that need phone support below the Custom tier.

The One Thing Their Marketing Won’t Tell You

SMS keyword automation is reported as inconsistent by G2 reviewers, and keyword campaigns are exactly the use case a retail or in-store brand would buy this for. Test your keyword flows during the trial rather than after you have migrated a list.

---

Attentive

Attentive is the enterprise SMS platform, with managed compliance backed by an in-house legal team and patented two-tap signup. It publishes no rate card at all, so every cost figure below is a third-party estimate rather than vendor pricing.

Attentive: What We Found in Testing

Four user interviews, all ecommerce brands above $5M ARR.

• Revenue attribution is the standout. The platform tracks financial impact per send and per automation rather than estimating from clicks, which is what makes the spend defensible internally.
• Onboarding is long but documented. Two users reported four to five weeks from contract to first live campaign, longer than any other platform here.
• Pricing opacity is an operational problem, not just a marketing complaint. One interviewee could not forecast next month’s invoice without calling their rep.
• Two-tap mobile signup is reported to lift opt-in rates 2 to 3x over standard forms, and cross-channel journeys combine SMS, email, RCS, and push notifications with AI-generated personalized text messages.
• 150+ native integrations cover Shopify, BigCommerce, WooCommerce, and Salesforce, with Attentive Signal handling real-time identity resolution.

Attentive Pricing

Cost component	Third-party estimate
Platform fee	$300 to $500/mo
Per SMS	$0.01 to $0.025
Per MMS	$0.02 to $0.03
Quarterly minimum	$2,000 to $3,000
Median annual contract (Vendr)	~$40,000, range $1,400 to $74,000
Onboarding	$2,000 to $25,000

Attentive publishes no pricing. Every figure above is a third-party estimate compiled from Vendr, CheckThat.ai, Eightx, and ATTN Agency, not verified Attentive pricing. Subscriber replies are reported as billable by ATTN Agency, which we could not verify with Attentive directly. AI add-ons carry separate unpublished fees.

Compliance

Fully managed 10DLC with a dedicated compliance team, and a legal team that will advise on campaign-level questions, which no other platform here offers. Double opt-in is enforced. SHAFT flagging is active. HIPAA BAA and EU data residency are both available. This is the strongest compliance posture in the comparison.

Who It’s For and Who Should Look Elsewhere

Attentive fits DTC brands above $5M in revenue with 50,000+ SMS subscribers who treat text as a primary revenue channel, and regulated industries needing a BAA plus legal support. It does not fit small businesses, startups, anyone below roughly $2M ARR, teams that need a forecastable invoice, or businesses where a four to eight week onboarding creates a problem. If you want that level of program management without the contract, an SMS marketing agency on a mid-market platform is usually the cheaper route.

The One Thing Their Marketing Won’t Tell You

Two brands sending identical volume can pay very different amounts. Reported contract values range from $1,400 to $74,000 a year, which means your price is a negotiation outcome, not a rate. Annual contracts with minimum spend commitments are standard and users report them as difficult to exit early, so read the cancellation and portability terms before signing.

---

Postscript

Postscript is the deepest Shopify SMS integration available, reading Shopify customer data (order history, browsing behavior, and cart contents) in real time through 45+ segmentation filters. It supports Shopify and nothing else, so a platform migration means rebuilding your SMS program from zero.

Postscript: What We Found in Testing

Three user interviews, all Shopify brands. Two had previously run SMS on Klaviyo.

• Subscriber capture happens at checkout. The integration covers Shopify, Shopify Plus, custom checkout pages, Carthook, and ReCharge, so list growth runs inside the purchase flow rather than beside it.
• Both migrators cited Shopify event trigger reliability as the reason they switched. You can fire a text when a customer replies with a keyword, begins checkout, or views a product.
• Revenue attribution reads directly from Shopify orders rather than estimating click-to-conversion, which is why the reporting holds up in a budget conversation.
• Infinity Testing generates thousands of message variants with AI and automatically ships the winner. All three users rated the testing framework above standard A/B tools because it covers offer structure and send timing, not just copy.
• The Shopify Flow connector on the Scale plan lets you trigger SMS from existing Flow workflows.

Postscript Pricing

Volume	Estimated monthly cost
5K sends/mo	~$75
50K sends/mo	~$750
500K sends/mo	~$7,500

Starter carries a $49/mo minimum at roughly $0.009/SMS and $0.045/MMS, plus applicable carrier fees. Growth runs about $100/mo plus per-message, Professional about $500/mo plus per-message, Enterprise is custom. All plans include a 30-day trial with $100 in credits. A revenue-share model based on a percentage of SMS-attributed revenue is also available. Carrier fees are not included in the rates above.

Compliance

Fully managed 10DLC through Twilio, with setup running anywhere from a few business days to several weeks. Double opt-in is enforced by default. SHAFT flagging is active. EU data residency is available on request.

Who It’s For and Who Should Look Elsewhere

Postscript fits Shopify-native brands at any scale where SMS attribution accuracy has to justify budget, and teams using large product catalogs to personalize SMS campaigns. It does not fit WooCommerce, BigCommerce, or Magento stores, brands that also need email in the same tool, international senders, or anyone who might change ecommerce platforms within two to three years.

The One Thing Their Marketing Won’t Tell You

MMS costs roughly 5x SMS, at $0.045 against $0.009, so an image-led campaign calendar burns budget far faster than the headline rate suggests. The claim that all incoming messages are free is also too absolute, because some inbound traffic still attracts carrier fees. Model the all-in number, not the advertised one.

---

SimpleTexting

SimpleTexting puts every feature on every plan, including API access, two-way texting, and AI Assist, with three user seats and rollover credits as standard. It is priced as a subscription rather than a per-message rate, so comparing it to Twilio on cost per text is the wrong comparison.

SimpleTexting: What We Found in Testing

I evaluated SimpleTexting for appointment reminders and promotional text messages. It is owned by Sinch and runs a credit-based model across nine tiers.

• 10DLC setup was the fastest documentation experience of the group. Approval came back in 1 business day.
• No feature gating is the genuine differentiator. Campaigns, autoresponders, segmentation, analytics, and API access are on the entry plan, which is unusual at this price.
• A/B testing covers message content, send timing, and offer type, which is more than most platforms at this tier allow.
• Support ticket median was 52 minutes across three test tickets. Phone support is available on higher plans.
• Unused credits roll into the next month, so a slow month does not vaporize your spend.
• The Shopify integration runs through Zapier. It handles order notifications and opt-in syncs, but it did not support real-time abandoned cart triggers reliably.

SimpleTexting Pricing

Volume	Monthly cost
500 credits	~$29 + $10 local number
3,000 credits	$119
7,500 credits	$239
25,000 credits	$559
50,000 credits	$909

Nine tiers total, from 500 credits to 50,000, with custom pricing above that. Annual billing takes 20% off. Overage runs about $0.055 per credit. MMS consumes 3 credits per message, so a 500-credit plan covers only 166 MMS sends. Extended messages of 161 to 306 characters consume 2 credits. A one-time $4 10DLC registration fee applies. Additional seats beyond the three included cost about $20/mo each.

Compliance

Built-in opt-in and opt-out handling, quiet hours, and 10DLC registration support. HIPAA coverage is partial and should be verified with their team before any healthcare use. There is no GDPR-specific tooling documented, and there is no EU data residency.

Who It’s For and Who Should Look Elsewhere

SimpleTexting fits small and mid-sized businesses that want campaigns, autoresponders, and two-way texting with no learning curve, plus teams that need a shared inbox for service-style text conversations. It does not fit ecommerce brands needing real-time product data, international senders, or high-volume programs where per-message economics dominate.

The One Thing Their Marketing Won’t Tell You

Seats are the hidden multiplier. Three are included, and each additional user costs about $20/mo, so a six-person team is paying roughly $99/mo before a single text goes out. Combined with 3-credit MMS and 2-credit extended messages, the real monthly number drifts well above the tier price.

---

TextMagic

TextMagic charges $0.049 per US SMS with no monthly subscription on the Essential plan and credits that never expire, which makes it the cheapest option for irregular volume. That same flat rate makes it the most expensive option at scale.

TextMagic: What We Found in Testing

I evaluated TextMagic for operational messaging: appointment reminders and delivery notifications.

• Sends to UK, Australian, and German numbers formatted sender IDs correctly per country, which several competitors handled inconsistently in the same test.
• The shared inbox aggregates SMS, email, WhatsApp, Facebook Messenger, and Instagram into one thread view, with basic CRM-style notes on contact records.
• Self-service 10DLC was the most friction-heavy process in the group. Budget 3 to 4 hours of work and roughly 10 business days before confirmation.
• EU sends run on EU-based infrastructure with documented GDPR compliance, and TCPA handling is automatic.
• Support quality is uneven. We hit no blocking issues, but we heard first-hand accounts of longer than usual waits on more technical tickets.
• BYOC lets you connect an existing CPaaS number for a $0.01/SMS platform surcharge, which changes the math if you already own numbers.

TextMagic Pricing

Plan	Cost
5K	$34.50
2K	$90/mo
10K	$370/mo
Pay-as-you-go	$0.035-0.045/SMS

A dedicated phone number costs $10/mo and 10DLC costs $10/mo. Inbound SMS is free.

Compliance

Self-service 10DLC registration with no managed pathway. Automatic TCPA opt-out handling. Documented GDPR compliance with EU infrastructure. No HIPAA path.

Who It’s For and Who Should Look Elsewhere

TextMagic fits businesses sending under roughly 2,000 messages a month, teams with unpredictable volume that cannot commit to a subscription floor, and service operations sending reminders and alerts internationally. It does not fit high-volume marketing senders, ecommerce brands needing store integration, or anyone who wants drip campaigns and behavioral segmentation, because this is operational texting rather than a marketing platform.

The One Thing Their Marketing Won’t Tell You

The 160-character limit collapses to 70 the moment you add an emoji, because Unicode encoding halves the segment size and each segment bills separately. At 10,000 messages the flat rate costs roughly $490 against roughly $83 on Twilio, and unnoticed segment splits widen that gap further. Our breakdown of how SMS character limits work covers what triggers a split.

---

SlickText

SlickText handles keyword opt-ins, QR code generation, SMS surveys, and automated campaigns built from drip sequences, on subscription tiers from $29 to $939 a month with rollover credits. Its carrier pass-through fee of about $0.0042 per SMS is billed separately, so the advertised tier is never the invoice.

SlickText: What We Found in Testing

• 10DLC registration is manual but assisted through support, and approval landed in 4 business days from signup, one of the fastest timelines we recorded.
• The keyword opt-in system, the “text JOIN to 12345” pattern, is well built and generates QR codes natively, which matters for in-store and print list growth.
• Pricing scales in discrete jumps that create cost cliffs. Moving up a tier can mean a 40% to 60% monthly increase for a small volume increase.
• A/B testing is limited to message copy. There is no testing on send timing, audience segment, or offer type.
• Scheduled campaigns and drip automations let you queue sequences across days or weeks, which covers standard triggered SMS use cases without complex branching.
• Contacts are unlimited on every plan, because pricing keys to message volume rather than list size.

SlickText Pricing

Credits	Monthly cost
500	$29
1,000	$49
2,000	$79
3,500	$129
10,000	$319
25,000	$579
50,000	$939

Carrier fees of about $0.0042/SMS are billed on top of credit cost. MMS consumes 3 credits. Annual billing adds two free months, roughly 16.7%. Several middle tiers changed during our testing window, so verify current pricing at slicktext.com/pricing.

Compliance

Built-in opt-in management, quiet hours that hold marketing messages back outside permitted send windows, and 10DLC support with assisted registration. Double opt-in is enforced by default and SHAFT flagging is active. There is no EU data residency because the infrastructure is US-only, and no GDPR tooling.

Who It’s For and Who Should Look Elsewhere

SlickText fits US-focused mid-market businesses running regular campaigns with predictable monthly volume, and brick-and-mortar or service brands growing lists through keywords and QR codes. It does not fit pay-as-you-go senders, ecommerce brands needing store data, teams requiring behavioral segmentation, or anyone wanting the lowest per-message rate.

The One Thing Their Marketing Won’t Tell You

There is no email channel and the ecommerce integration set is thinner than Omnisend, Klaviyo, or Postscript. If SMS is meant to work alongside email in a single sequence, you will be wiring two platforms together and reconciling two sets of reporting.

---

Textla

Textla charges a flat monthly base plus $0.01 per SMS segment with no credit buckets, so you pay only for what you send. The feature set is deliberately narrow, which is the trade-off you accept for that simplicity.

Textla: What We Found in Testing

• 10DLC setup runs through Twilio with clear guidance. Our team completed account setup and submitted registration in under 2 hours, with Textla handling approval and follow-up.
• Double opt-in is enforced by default, SHAFT flagging is active, and EU data residency is available through Ireland’s IE1 region for GDPR.
• The contact management interface is unusually clean. Filtering and segmenting a 10,000-contact list took minutes, where competing platforms took 20 minutes or more of navigating modal layers.
• What it does not have: AI personalization, send-time optimization, or the advanced features a full marketing platform brings, drip campaigns included. That is a deliberate product decision, not an oversight.
• The API is functional but thin. Integrating SMS into a wider martech stack through webhooks or custom triggers hits limits quickly.
• Support ticket response ran a median of 47 minutes across three test tickets, the fastest in the group.

Textla Pricing

Volume	Estimated monthly cost
5K sends/mo	~$75
50K sends/mo	~$525
500K sends/mo	~$5,025

Starter runs about $25/mo, or $19/mo billed annually, plus $0.01 per SMS segment. The figures above use the monthly base. There are no credit buckets, so nothing expires unused. Verify at textla.com/pricing.

Streamlined 10DLC through Twilio with the vendor handling approval and follow-up. Enforced double opt-in, active SHAFT flagging, and EU data residency through the IE1 region.

Who It’s For and Who Should Look Elsewhere

Textla fits very small businesses under roughly 2,000 messages a month moving off manual texting or spreadsheets, and teams that need to be operational in a day without technical help. It does not fit ecommerce brands needing Shopify triggers or behavioral segmentation, high-volume marketers, enterprises, or anyone who needs drip campaigns and advanced list segmentation.

The One Thing Their Marketing Won’t Tell You

It is a comparatively new platform with a small user base and limited third-party review data, which means there is little independent evidence about reliability at scale. Trustpilot sits at 3.1 against 5.0 on G2 and Capterra, and that spread on a low review count is worth investigating before you migrate a list.

Textedly

Textedly starts at about $29/mo for 500 monthly messages and does the basics: campaigns, MMS, text-to-join keywords, autoresponders, and scheduling. Its $0.05 overage rate is among the highest here, which punishes exactly the growth it is meant to support.

Textedly: What We Found in Testing

• Setup was straightforward with no meaningful onboarding friction.
• The interface improved through 2025 but still trails SlickText and SimpleTexting in polish.
• Assisted 10DLC registration completed in 4 business days in our test, although documentation says it can take up to two weeks.
• TCPA opt-out is handled automatically, but there is no proactive SHAFT flagging and no EU data residency, which rules it out for regulated industries and EU-primary audiences.
• No A/B testing, no send-time optimization, and no native Shopify integration beyond Zapier.
• The integration ecosystem has expanded. Textedly now promotes connections with a considerably larger set of third-party tools than its original list.

Textedly Pricing

Volume	Estimated monthly cost
600 messages	~$29
6K sends/mo	~$169
60K sends/mo	~$1,020

The entry plan runs about $29/mo for 600 messages on monthly billing, and older annual rates may have been lower. Pricing scales with message volume on a credit model. Overage runs about $0.05 per text once the bundle is used. Tier details above 50,000 are not clearly published. Verify current tiers at textedly.com/pricing.

Compliance

Assisted 10DLC registration with automatic TCPA opt-out handling. No proactive SHAFT flagging, no GDPR tooling, no EU data residency, and no HIPAA path.

Who It’s For and Who Should Look Elsewhere

Textedly fits very small local businesses, salons, gyms, churches, restaurants, and solo operators sending promotions and reminders to a modest list, usually with a small library of reusable text message templates. It does not fit ecommerce brands needing behavioral triggers, regulated industries, international senders, or any business expecting SMS to become a primary revenue channel.

The One Thing Their Marketing Won’t Tell You

Automation depth is the ceiling nobody mentions at signup. There are no behavioral triggers, no conditional branching, and no purchase-based flows, so the platform runs out of room at roughly the point your list starts producing real revenue. Combined with the $0.05 overage rate, growth costs more here than at almost any competitor.

EngageBay

EngageBay bundles SMS into a CRM-first platform alongside email, live chat, landing pages, and a help desk, from the Basic tier of Marketing Bay, so a small team can cover four channels without buying other tools for each one. SMS is a supporting channel here, not the product, and the depth reflects that.

EngageBay: What We Found in Testing

• SMS automation is functional but noticeably shallower than dedicated platforms. Users described treating text as a supplement to email workflows rather than a channel of its own.
• The CRM integration is the actual differentiator. SMS activity sits alongside email, deals, notes, tasks, and customer history in one record, which matters for service teams managing conversations rather than campaigns.
• Campaigns can be triggered by CRM events such as deal stage changes, form submissions, and tag assignments, and email plus SMS plus CRM actions combine in a single sequence.
• 10DLC setup is self-service with limited guided support, and approval typically takes 10 to 15 business days.
• TCPA opt-in is configurable but not enforced. There is no documented HIPAA path and no EU data residency.
• The interface feels crowded given how much is bundled into it.

EngageBay Pricing

Marketing Bay runs Basic, then Growth, then Pro. SMS is available from Basic. No Enterprise tier appears on the standard Marketing Bay pricing table.

SMS starts at Basic for $14.99/month.

Compliance

Self-service 10DLC with limited guidance and 10 to 15 business day approval. Configurable but unenforced TCPA opt-in. No GDPR tooling, no EU data residency, no HIPAA path.

Who It’s For and Who Should Look Elsewhere

EngageBay fits small service businesses, agencies, and solo operators that want CRM, email, and SMS in one subscription without Salesforce pricing, and that treat text as a follow-up channel inside a broader marketing automation workflow. It does not fit ecommerce brands, SMS-heavy marketers, high-volume senders, regulated industries, or any brand with EU subscribers.

The One Thing Their Marketing Won’t Tell You

Plan names and pricing have changed, and SMS rates are not on the public page, so the total cost of the SMS channel is not knowable before you talk to them. For a platform whose entire pitch is affordability against enterprise suites, that is the one number you would expect to find published.

EZ Texting

EZ Texting has run since 2004 and pairs AI Compose message drafting with a 6,000-image Shutterstock library for MMS, which no other platform here bundles. Its plan structure is the most misreported in the category: Boost and Scale both include 500 base credits, not 2,000 and 5,000.

EZ Texting: What We Found in Testing

• AI Compose generates campaign copy from a short prompt, and the Shutterstock library removes the usual scramble for a licensed image when an MMS campaign needs a visual.
• Drip automation handles scheduled message sequences, and list growth runs through text-to-join keywords, QR codes, and signup forms.
• The plan tiers do not work the way most comparisons describe. Boost at $75/mo and Scale at $125/mo both include 500 base monthly credits. What actually changes between them is the overage rate and feature access, so buying up a tier to get more included messages is a mistake.
• The Launch plan carries a $5 monthly telecom fee, which makes the real entry cost $30/mo rather than the advertised $25.
• Monthly credits can roll into the next billing period. Annual credit rules differ, so the blanket claim that credits expire after 12 months is not accurate across plans.
• Additional users cost $10/mo each, so a 4-person team on Launch is at $55/mo before sending anything.

EZ Texting Pricing

Plan	Monthly cost	Included credits
Launch	$25 + $5 telecom fee	500
Boost	$75	500, lower overage
Scale	$125	500, lower overage
Enterprise	Custom	Custom

Plans span roughly $25 to $3,000/mo depending on volume and team size. MMS consumes 3 credits. Additional users cost $10/mo each. Overage rates decrease on higher tiers but are not published as a single figure, so cost at 5,000 sends and above cannot be modeled from public pricing. Verify current credit structure and registration charges at eztexting.com/pricing.

Compliance

10DLC registration is assisted through the platform. Emoji use switches messages to Unicode encoding, which cuts the character limit and increases credit consumption per send, so compliance-safe copy and cost control pull in the same direction here.

Who It’s For and Who Should Look Elsewhere

EZ Texting fits marketing teams sending 1,000 to 15,000 messages a month who want AI drafting and stock imagery included, and who track campaign performance through basic SMS click-through reporting. It does not fit pay-as-you-go senders, teams that need all-in pricing published before signup, or high-volume programs, where SlickText and SimpleTexting both deliver more messages per dollar.

The One Thing Their Marketing Won’t Tell You

Moving from Launch to Scale multiplies your bill by five and gives you exactly the same 500 included credits. You are buying a lower overage rate and more features, which may be the right purchase, but the plan names imply a volume upgrade that is not there.

Twilio

Twilio is raw SMS infrastructure at $0.0083 per US message, the lowest rate in this comparison, and it powers Postscript, Textla underneath. There is no campaign builder, no contact management, and no templates, so it takes developer time to send a single text.

Twilio: What We Found in Testing

• The per-message economics are genuinely different. At 50,000 sends the message cost is $415 against roughly $939 in credits on SlickText, before either side’s carrier fees.
• Programmable Messaging covers SMS, MMS, WhatsApp, RCS, and voice through one API, with local number provisioning across 190+ countries.
• Two-way messaging, automated responses, and conversation tracking all exist, but as API primitives you assemble rather than screens you configure.
• CodeExchange ships pre-built integrations and sample code, which shortens the build for common patterns without removing the need for engineering.
• You build compliance yourself. Opt-out handling, quiet hours, and consent capture are your responsibility. Twilio supplies tools, not a managed program, which is the opposite of what Attentive or Postscript sell.
• International rates climb steeply. EU sends run roughly $0.04 to $0.08, and Asia varies significantly by country.

Twilio Pricing

Item	Cost
SMS (US outbound)	$0.0083/segment
MMS (US)	~$0.022/segment
Inbound SMS	$0.0083/segment
Local phone number	$1.15/mo
Toll-free number	$2.15/mo
10DLC registration	$2/campaign/mo + one-time brand vetting $4 to $44

There is no monthly platform fee. Carrier fees run roughly $0.003 to $0.005 per message and vary across AT&T, T-Mobile, and Verizon, so a single all-in figure would be imprecise. Volume discounts start above 1 million messages. Production support starts at the greater of about $250/mo or 4% of monthly spend, which is the line item most cost comparisons omit.

Compliance

Self-service 10DLC through the API at $2 per campaign per month plus one-time brand vetting. Everything else, opt-out processing, quiet hours, consent records, is built and maintained by you.

Who It’s For and Who Should Look Elsewhere

Twilio fits developer teams embedding SMS into their own product and high-volume transactional senders where per-message cost outweighs interface convenience, especially teams already instrumenting their own messaging metrics. It does not fit marketers, small business owners, or any team without engineering capacity, because there is no way to create campaigns without writing code.

The One Thing Their Marketing Won’t Tell You

The $0.0083 rate is not your cost. Add carrier fees, numbers, 10DLC registration, and production support at $250/mo or 4% of spend, and a small program can land above a mid-market platform that includes a builder, seats, and a compliance team. Twilio wins on unit economics at volume, and loses on total cost below it.

SMS Platform Migration: Costs, Timelines, and Risks

This section is for teams already running an SMS service somewhere else. Switching is rarely as clean as the sales call suggests, and three parts of your SMS strategy carry real risk: consent records, phone numbers, and automations.

What You Lose When Switching

Subscriber consent portability. Your customers’ phone numbers and opt-in status usually export cleanly. The proof of consent, meaning timestamp, source, and opt-in method, often does not export completely. In a TCPA dispute that documentation is your defense, so export and archive every consent record your current platform holds before you cancel anything.

Phone number porting. Long codes, toll-free numbers, and short codes can usually be ported, but timelines and processes vary widely by platform and carrier. Start the port before you rebuild, not after.

Automation rebuild. Every flow you have built has to be rebuilt from scratch on the new platform. There is no universal export format for SMS automation workflows, which is why the rebuild, not the data migration, is where the hours go.

Platform	Number porting in	Number porting out	Typical timeline
Sender	Yes	Yes	7 to 14 business days
Klaviyo	Yes	Yes	10 to 21 business days
Omnisend	Yes	Yes	7 to 21 business days
Attentive	Yes	Yes, with notice	14 to 30 business days
Postscript	Yes	Limited, short codes only	14 to 21 business days
SimpleTexting	Yes	Yes	5 to 14 business days
TextMagic	Yes	Yes	5 to 14 business days
SlickText	Yes	Yes	10 to 21 business days
Textla	Yes	Limited	14 to 21 business days
Textedly	Yes	Yes	10 to 21 business days
EngageBay	Limited	Limited	Verify before committing
EZ Texting	Verify	Verify	Verify before committing
Twilio	Yes	Yes	7 to 21 business days

Porting timelines are estimates based on platform documentation and user reports. Actual timelines depend on your current carrier and number type.

If Sender is where you are heading, our team handles the list import, consent records, and flow rebuild for you through the migration service, including on the free plan.

How Long Does SMS Platform Migration Take?

Migration task	Estimated hours
Export subscriber list and consent records from current platform	1 to 2 hours
Clean and format the list for import	2 to 4 hours
Account setup and 10DLC registration	2 to 4 hours managed, 6 to 10 hours self-managed
Rebuild core automations (welcome, abandoned cart, post-purchase)	4 to 12 hours depending on complexity
Test sends and deliverability verification	2 to 4 hours
Number porting and cutover	Waiting time only, see table above
Total on a managed 10DLC platform	~12 to 26 hours
Total on a self-service 10DLC platform	~18 to 36 hours

Text is one channel inside a wider marketing mix, and the platform you pick for SMS usually needs to sit beside whatever sends your email. If you are reviewing both at once, start with our complete email marketing guide and settle the strategy before the tooling.

Once that is clear, compare your SMS shortlist against the wider field of email marketing services and check which of them already send text from the same account. Running one platform for both channels is usually cheaper than running two, and it is the single biggest cost variable in this entire comparison.
