Mailjet Pricing: Plans, Costs & Best Value Analysis (2026)

I’ve dug through Mailjet’s pricing plans more times than I’d like to admit, and honestly? The fine print matters way more than the headline numbers once you’re sending real volume. Daily limits, integrations, nonprofit discounts—these questions don’t come up until you’re past the testing phase and trying to run email marketing campaigns for real. 

I put this Mailjet review together to show what applies in production, especially if you’re weighing Mailjet against other email marketing tools or thinking long-term. Whether it’s newsletters, automation, or transactional email you’re after, these details should keep you from any unpleasant surprises.

Mailjet Pricing at a Glance

Mailjet Plans & Costs Reviewed

Free Plan Reviewed

Some people call it a generous free plan, but it’s really only good for kicking the tires—testing deliverability, poking around the API, seeing how the editor feels. You can get set up in just a few minutes, and even novice users can figure out the basics. But running real campaigns on it? Not happening. 

That 200 emails/day cap will stop you cold, even for modest bulk emails or a product launch. No automation, no team access, and the Mailjet logo stuck on everything. Most people I’ve talked to end up upgrading within a week or two once they try to schedule a campaign, want branding gone, or realize their list is bigger than a few hundred active subscribers.

Essential Plan

Essential is decent if you’re a solo operator or small team sending newsletters and don’t need automation yet. Paid plans start at $17/month here, and you get rid of daily caps, branding is gone, and monthly volume is predictable. But that’s about it. No email automation, no A/B testing, no way to add teammates for multi-user collaboration. 

The single-user limit gets annoying fast when someone else needs to review drafts or send something while you’re out. Give it a month or two and you’ll probably want welcome sequences, triggered emails, or at least some basic testing. Think of this tier as a stepping stone, not somewhere you’ll stay.

Premium Plan

This is where Mailjet starts feeling like a real marketing tool. Premium is the minimum I’d recommend for anyone doing lifecycle email—SaaS companies, ecommerce, content teams running automations and experiments. You also get access to landing pages and email tracking to see how campaigns perform across different email clients. If email is tied to revenue or keeping customers around, you need to be here at least. 

Fair warning though: costs climb faster on this tier because volume, user seats, and support quality all depend on which sub-tier you pick. The reporting and permissions are still lighter than dedicated enterprise tools. You’ll feel the squeeze when you need deliverability controls, SLA commitments, or finer-grained access management—usually once volumes go up or email becomes genuinely critical to the business.

Custom Plan

Custom is for high-volume senders or anyone with serious compliance requirements who can’t afford delivery hiccups. If you need SLAs, a dedicated IP strategy, hands-on onboarding, advanced permissions, or limits built around your situation, this is where you end up. 

Pricing moves from self-serve to negotiated contracts—more procurement hassle, but more flexibility too. People don’t usually move to Custom for features. They move because of risk: traffic spikes, sender reputation concerns, regulatory stuff. Smaller teams won’t need this. Bigger senders often don’t have a choice.

Mailjet Hidden Fees & Extra Costs

The sticker price looks clean, but real Mailjet fees sneak up on you as you scale. Unused monthly credits? Gone at the end of the month—no rollover. That quietly raises your effective Mailjet cost per email. Need a dedicated IP, reputation monitoring, or someone to walk you through onboarding? Not included on standard plans. 

You’re looking at higher Premium tiers or jumping to Custom. User seats and permissions are capped on lower plans, so adding teammates forces an upgrade. Same goes for priority support, SLAs, SSO, audit logs—all gated behind pricier tiers. These aren’t technically “hidden,” but they add up faster than you’d expect.

Mailjet Pricing by Monthly Email Volume

Mailjet Pay-As-You-Go Email Costs

Mailjet does not offer a true “pay-as-you-go” plan where you buy a tiny amount of credits and only pay per email with no subscription attached. What they have instead is subscription-based pricing with included monthly email volumes and additional charges if you go over that volume.

Mailjet Transactional Email Pricing

Important note for power users: Premium unlocks “ops-grade” extras that matter for transactional reliability—e.g., chat/phone support starts at 50k, and a dedicated IP becomes available starting at 100k tiers.

Transactional Plans Breakdown

Mailjet doesn’t have a separate transactional product. Your transactional sends just come out of your regular email volume via SMTP relay or API. That’s convenient if you’re mixing marketing and transactional under one roof—one bill, one pool of credits. 

The downside is that transactional reliability depends on your plan tier. Lower tiers don’t get dedicated IPs or serious deliverability controls, which can bite you in production. As volume grows, most people sending anything important end up moving to higher Premium tiers or Custom for the stability and support.

Per-Email Costs by Volume

Transactional costs drop predictably as volume goes up, but the curve isn’t steep. At lower tiers, you’re paying over $1 per thousand sends—higher than a lot of API-first providers. Things only get competitive around 100k+ monthly. 

And because marketing and transactional share the same pool, a sudden spike can bump you into the next tier without warning. For steady, high-volume transactional traffic, Mailjet can work. But it’s rarely the cheapest option out there.

Mailjet SMS Pricing & Costs

SMS marketing pricing is usage-based—you pay per message. What you’ll pay mostly depends on the destination country (carrier fees, local regulations) and how much volume you’re doing (bigger volumes usually mean lower per-SMS rates).

Looking at Mailjet’s docs and some third-party reviews, the rates vary quite a bit by region rather than being one flat number.

Mailjet vs Competitors: Which Costs Less?

Is Mailjet Worth the Price?

My take: Mailjet earns its price when you want straightforward volume-based pricing for newsletters or mixed marketing/transactional email without getting taxed on list size.

As an email provider, it’s also solid if you value clean SMTP/API access and don’t need a sprawling marketing suite. Novice users will appreciate the intuitive interface, and the ability to send an unlimited number of emails on higher tiers is a nice touch.

When should you look elsewhere? Mailjet isn’t the perfect tool for everyone. Ecommerce brands often do better with Klaviyo’s store-focused automation. Developer teams tend to prefer SendGrid or Mailgun for the infrastructure-first approach.

Enterprises with heavy governance and integration requirements might need something like Salesforce Marketing Cloud or Adobe Campaign. And if you’re just trying to scale general email marketing without spending much, Sender often delivers more for less.
