I Compared Sender vs Omnisend in 2025 – Here Is What I Found

Sender includes product blocks for ecommerce campaigns, making it easier than many competitors to showcase your products in emails. You get A/B testing (up to 8 combinations), scheduling, and segmentation—the features that actually move the needle. What impressed me was how Sender includes these on the free plan, while many competitors lock them behind paid tiers. 

Omnisend gives you everything you’d expect from an ecommerce-focused platform. The campaign builder pulls in product recommendations automatically, includes dynamic discount codes, and even lets you add scratch cards or gift boxes for engagement.

I found the product picker particularly useful—you can drag items from your store directly into emails without wrestling with image uploads or links.

Winner: Sender offers more flexibility for general email marketing campaigns, but Omnisend edges ahead for ecommerce with its automatic product features.

Both platforms use drag-and-drop editors, but they feel distinctly different in practice. 

Sender’s editor is intentionally uncomplicated: drag-and-drop, quick personalization, and fast output. The template library is smaller, but the email templates are well-designed and adaptable.

I could create a professional newsletter in about 10 minutes without touching any code. For those who need it, custom HTML editing is fully supported—you can add custom HTML blocks within the drag-and-drop editor or import complete HTML templates via URL or file upload.

Omnisend’s editor is optimized for showcasing products—you’ll find pre-built sections for product grids, recommendations, and promotional blocks. The 350+ templates lean heavily toward promotional content, which makes sense for their ecommerce focus.

Winner: Sender for general newsletters and simpler campaigns; Omnisend for ecommerce stores needing product-focused designs.

Sender offers SMS automation that integrates with email workflows. You can create multi-channel sequences combining email and SMS steps with triggers, conditions, and delays.

While not as deeply integrated as Omnisend’s omnichannel approach, Sender lets you build workflows where email and SMS work together—like sending an abandoned cart email followed by an SMS reminder. You’ll need to buy SMS credits separately (Pro users get free credits), but it’s solid for basic SMS campaigns at a lower cost than specialized platforms.

Omnisend treats SMS as a first-class citizen alongside email. You can build omnichannel workflows where a customer receives an email, then gets a text reminder an hour later—all from one automation.

The SMS editor includes smart features like dynamic discount codes and product links that actually work on mobile. The platform supports international SMS to 200+ countries and regions  and includes SMS credits with Pro plans. What makes it stand out is the behavioral segmentation—you can target customers based on purchase history and engagement patterns across both channels.

Winner: Omnisend for businesses needing sophisticated SMS marketing with deep behavioral analytics and seamless omnichannel workflows. However, Sender is a solid choice if you just need basic SMS functionality alongside email—it gets the job done at a lower cost without the complexity of advanced segmentation and analytics.

Sender’s workflow builder is straightforward and visual for email + SMS automations: delays, conditions, actions (move/copy/remove from groups, update fields), and webhooks. It’s lighter on bells and whistles but covers the automations most teams need. 

This is where Omnisend really flexes. The automation builder lets you combine email, SMS, and push notifications in sophisticated workflows.

I set up an abandoned cart sequence that sent an email after 1 hour, an SMS after 4 hours, and a push notification the next day—all from one workflow. The pre-built templates for welcome series, post-purchase flows, and win-back campaigns save hours of setup time.

Winner: Both platforms offer solid SMS automation for ecommerce businesses, but Omnisend takes the edge with its additional push notification capabilities that create truly omnichannel workflows.

Both platforms let you create signup forms and landing pages with gamification features to boost conversions.

Sender’s forms are clean, functional, and load fast without hurting site performance. You get popups (including exit-intent, scroll depth, etc.), embedded forms, and landing pages covering all the essentials with straightforward targeting options. The platform also includes spin-to-win wheel popups where visitors spin for rewards like discount codes or free shipping.

Omnisend offers Wheel of Fortune popups, scratch cards, and gift boxes—all designed specifically for ecommerce. Omnisend also includes teaser popups that showcase products before asking for emails, which feels less pushy than standard discount offers. You can set advanced targeting rules based on exit intent, scroll depth, URL, and behavioral triggers.

Winner: Omnisend for creative signup experiences; Sender for straightforward, fast-loading forms.

Sender supports smart segments based on behavior/attributes and keeps the UI approachable. The segmentation strikes a balance between power and usability, giving you the targeting capabilities that actually drive results. You can segment by opens, clicks, tags, and custom fields without getting overwhelmed by options.

Omnisend’s segmentation gets granular. You can target customers who bought a specific product category in the last 30 days but haven’t opened an email in 14 days. The Customer Lifecycle Map visualizes your audience journey, showing you exactly where subscribers fall in their buying cycle. It’s data-heavy, but incredibly useful for ecommerce targeting.

Winner: Omnisend for ecommerce businesses needing deep behavioral insights; Sender for simpler engagement-based segmentation.

Sender supports major ecommerce platforms like WooCommerce, Shopify, Magento, and BigCommerce through reliable integrations. You can send cart abandonment emails, track purchases, and use product blocks in campaigns. But you’ll be doing more manual work to set things up compared to Omnisend’s plug-and-play approach.

Omnisend was built for this. Deep integrations with Shopify, BigCommerce, and WooCommerce pull in order data, product catalogs, and customer behavior automatically. The abandoned cart emails include product images, prices, and direct purchase links. Product recommendation blocks use AI to suggest items based on browsing and purchase history.

Winner: Omnisend—the ecommerce features are comprehensive and purpose-built. Sender works well for basic ecommerce needs at a lower cost, just not as deeply integrated.

Sender emphasizes deliverability as a core strength. They maintain strong ISP relationships and offer authentication setup support. In my testing, Sender consistently achieves solid inbox placement rates.

The platform includes list hygiene tools and actively prevents spam-related issues. Sender also includes SMTP service as part of their platform (not as a separate feature), making it easy to integrate email sending into your applications or website.

Omnisend provides full SPF, DKIM, and DMARC authentication with an intuitive setup wizard. They have a dedicated deliverability team and offer IP warmup support for high-volume senders. The deliverability dashboard gives you visibility into sender health, though I noticed they don’t provide actual deliverability scores like some competitors do.

Winner: Slight edge to Sender based on consistent user feedback about inbox placement and included SMTP service, though both platforms handle deliverability fundamentals well.

Sender keeps reporting simple and actionable. You get the metrics that matter—opens, clicks, unsubscribes, bounces, and conversions. The reports load fast, export easily, and give you enough data to optimize without overwhelming you with charts.

Omnisend’s reporting is built around revenue. Every campaign shows not just opens and clicks, but actual sales generated and attributed revenue. The heatmaps show exactly where people clicked in your emails. The only downside? Advanced reporting features are locked behind the Pro plan, which starts at $41 a month.

Winner: Omnisend for ecommerce stores tracking revenue; Sender for straightforward campaign analytics at a better price.

Sender offers 160+ integrations through direct connections and Zapier. You’ll find the major ecommerce platforms covered—Shopify, WooCommerce, Magento, BigCommerce. The integrations work reliably, but they’re more functional than Omnisend’s deeply embedded ecommerce features.

Omnisend integrates natively with 30+ platforms, but the Shopify integration is where they shine. One-click setup, automatic product sync, and seamless data flow. They also connect with review apps like Judge.me and Yotpo, giving you more tools to build social proof in emails.

Winner: Omnisend for ecommerce depth; Sender for breadth across different business types.

Sender provides 24/7 email and live chat support on all plans, including free. Response times are consistently quick, and the support quality stands out—the team tackles technical issues like DNS setup and authentication configuration, not just basic platform questions. The knowledge base is comprehensive with clear documentation for most common scenarios.

Omnisend offers 24/7 live chat and email support on all plans, including free. In my tests, response times averaged under 5 minutes—impressively fast. The support team knows ecommerce, not just the platform. You also get access to a customer success manager once you’re spending $400+/month, though that seems like a high threshold for personalized support.

Winner: Tie. Both platforms offer excellent, accessible support.

Sender differentiates with its pay-as-you-go credit system (perfect for seasonal senders), unlimited email storage without contact limits increasing costs, dedicated IPs available at lower tiers, and remarkably fast email sending speeds. These features appeal more to businesses with irregular sending patterns or tight budgets.

Omnisend’s standout features include the Customer Lifecycle Map (visualizes where customers are in their journey), Product Reviews collection and display for Shopify stores, Google Customer Match integration, and Facebook Custom Audiences sync. These are genuinely useful features for ecommerce marketers building cross-platform campaigns.

Winner: Depends on your business model—Omnisend for ecommerce sophistication, Sender for pricing flexibility.

G2 reviewers are fans of Sender’s drag-and-drop editor and how fast you can get campaigns up and running. The automation tools are solid, and people love that the free plan is actually generous enough for small businesses to get real value. Reporting is simple to understand, emails reliably reach inboxes, and support is top-notch.

The main complaint? They’d like more pre-made templates, though most agree the customization options make up for it.

People on G2 really like Omnisend’s smooth integrations and clear pricing—no hidden surprises. The customer support gets thumbs up for being quick and helpful, and setting up email automations is pretty straightforward.

On the flip side, users wish the API docs were more detailed, and navigating complex automations can get a bit tricky. Some also mention wanting better segment-based reporting and note that Shopify tag syncing doesn’t always work perfectly.

Users love Sender for its solid features, intuitive interface, and competitive pricing that’s perfect for non-profits and small businesses. The support team gets rave reviews for being incredibly responsive and proactive about fixing issues.

People appreciate the easy-to-use drag-and-drop editor and the platform’s continuous improvements.

Users find Omnisend easy to use once you get the hang of it, with great tools for creating beautiful emails and a super responsive support team.

However, the initial setup can be tricky if you’re not tech-savvy, and some settings lack clear explanations. People also wish there were more templates and deeper analytics available for tracking campaign performance.

Reddit users rave about Sender’s genuinely usable free plan, which includes up to 2,500 subscribers and 15,000 emails per month—a refreshing change from typical “free” services with major limitations.

People love the excellent deliverability, tons of templates, and how easy the platform is to use. The support team actually helps when needed, making it a solid choice for those burned by other providers with restrictive free tiers.

Reddit users have mixed opinions on Omnisend. Many switched from pricier competitors and appreciate the solid feature set, including automations, SMS marketing, and integrations, all at a better price point. The platform is praised for being reliable and hassle-free for ecommerce stores.

However, some users report frustrating experiences with buggy features and underwhelming customer support, particularly on higher-tier plans, with technical issues taking too long to resolve.

Sender includes SMTP service by default but doesn’t let you use external SMTP servers. Omnisend uses its own proprietary sending infrastructure and provides API access for transactional emails, but does not offer SMTP relay service. If you specifically need to use your own SMTP server, you’d need to look at platforms like Mailchimp or SendGrid that offer SMTP relay services.

Based on user reviews and testing, both platforms maintain strong deliverability through proper authentication (SPF, DKIM, DMARC) and list management practices. Sender receives slightly more consistent praise for inbox placement, but your actual deliverability depends more on your sending practices, list hygiene, and email content than the platform itself.

Yes, both platforms support CSV imports for contacts and provide migration assistance. However, you’ll need to rebuild your automation workflows from scratch, as these don’t transfer between platforms. Budget 2-3 days for a complete migration including testing.
