Mailjet vs Brevo: Which Email Platform Wins in 2026?

Picking between Mailjet and Brevo usually comes down to one question: are you sending email as a developer who wants clean APIs and team-friendly templates, or are you a small business that wants email, SMS, and a CRM under one login? The two tools overlap on the surface, but they're built for different people.

Mailjet, owned by Sinch since the Pathwire acquisition closed in December 2021, leans toward transactional and marketing email with strong template collaboration and EU data hosting. Brevo, the platform formerly known as Sendinblue, bundles email with SMS and light sales/contact tools and is mainly priced by emails sent, though current paid tiers also include contact-storage caps. That pricing difference shapes which tool is cheaper for your situation, and it's where most people make the wrong call.

This is a fair comparison, not a takedown of either tool. Below you'll find verified 2026 pricing, an honest read on deliverability, and a verdict by use case. At the end, you'll see where an AI-native option like Dreamlit fits if you're building on Supabase.

At a Glance

Pricing is current as of 2026 and changes often; confirm on each provider's site.

Mailjet in Brief

Mailjet started as a developer-first email service and still shows that DNA. You get a solid SMTP relay and Send API for transactional mail, a drag-and-drop editor, and a feature that genuinely sets it apart: real-time collaboration on templates. Multiple teammates can edit the same template at once, leave comments on specific blocks, lock design sections so nobody breaks the brand, and restore old versions. If you've ever fought with a colleague over who overwrote whose email layout, you'll appreciate it.

The catch is that automation and A/B testing live on the Premium tier, and the headline collaboration features sit on higher paid plans. Mailjet's free and lower paid plans are capable but stripped of some of the parts that make it stand out. Being part of Sinch also means SMS is technically in the family, but it routes through Sinch rather than sitting natively in the Mailjet marketing dashboard.

Brevo in Brief

Brevo casts a wider net. One account covers email marketing, transactional email, SMS, WhatsApp, light sales/contact tools, and even landing pages on higher tiers. For a small business that wants to run campaigns, track contacts, and text customers without stitching three tools together, that breadth is the whole pitch.

The trade-offs are real. The interface carries a lot of surface area, which can feel busy if you only came for email. Marketing automation and A/B testing are gated to the Standard tier and above, so the cheapest paid plan won't get you the workflow builder. And while the free plan stores up to 100,000 contacts, the 300-emails-per-day cap on free means you'll outgrow it quickly if you send daily.

Pricing Model

This is the most important section, because Mailjet and Brevo price email in fundamentally different ways.

Mailjet charges by the number of emails you send per month, with contact storage mostly along for the ride. The free plan gives you 6,000 emails a month but throttles you to 200 per day. Paid tiers in 2026 look roughly like this:

Brevo charges mainly by emails sent, but current paid tiers also include contact-storage caps. The free plan stores up to 100,000 contacts and caps sending at 300 emails per day. Paid email plans in 2026 look roughly like this:

Note that Standard plan pricing scales with send volume, so the ~$18 entry point is for the lowest 5,000-email bucket and rises as you add volume. Standard supports up to 500,000 monthly emails; Professional starts around $499 for 150,000+ emails and supports much higher volumes before Enterprise. Treat any number above the Starter tier as volume-dependent and get a live quote for high volumes.

A worked example makes the difference clear. Say you have 40,000 contacts but only email the full list twice a month, so 80,000 sends. With Brevo's model, you pay mainly for roughly 80,000 emails, but you still need a tier whose contact-storage quota fits your list. With Mailjet, the same 80,000 monthly sends pushes you into a higher volume bracket regardless of how many contacts you keep. For large lists you email occasionally, Brevo can win on price. Flip the scenario, say a smaller list you email every single day, and Mailjet's steady-volume tiers can come out cheaper because you're not bumping against a daily cap or a contact-storage assumption.

Deliverability

Both platforms post competitive deliverability, and neither holds a consistent, decisive lead across independent audits. Brevo runs on a mix of shared and dedicated IPs and gives you authentication tools out of the box. Mailjet, with its developer history and Sinch infrastructure behind it, also lands reliably when configured correctly.

The honest truth is that your sender reputation matters more than the logo on the dashboard. Authenticate your domain with SPF, DKIM, and DMARC, warm up new sending domains gradually, prune inactive subscribers, and keep complaint rates low. Do that on either platform and you'll see strong inbox placement. Skip it, and the best ESP in the world won't save you. Our deliverability guide walks through the setup that actually moves the needle.

One practical difference does show up at the IP level. On shared IP pools, your deliverability is partly tied to the behavior of other senders sharing that pool, which is why both platforms screen new accounts and why a sudden spike in sending can trip throttles. A dedicated IP isolates your reputation, but it's a paid add-on on Brevo's higher tiers and on Mailjet's Premium and custom plans, and it only helps if you send enough volume to keep that IP warm. For most small and midsize senders, a well-managed shared IP on either platform is the right call. If you're sending hundreds of thousands of messages a month, that's when a dedicated IP starts to pay off, and both tools support it.

Verdict: A tie on raw capability. Both reward good sending habits and punish bad ones equally.

Automation and Workflows

Brevo's automation is the more visible part of its product. The workflow builder handles welcome series, abandoned-cart flows, lead scoring, and multi-step branching based on contact behavior. The important caveat: it's gated to the Standard tier and up. The free and Starter plans don't include the automation builder or A/B testing, so budget for at least the Standard plan if workflows are central to your plan.

Mailjet's automation is more modest. You can trigger emails based on actions and use pre-built automation templates, but the depth lives on the Premium tier alongside A/B testing. Mailjet's standout isn't the automation engine; it's the collaborative template workflow, where a team can build, comment on, and version emails together in real time.

Verdict: Brevo for richer marketing automation, as long as you're on the Standard tier. Mailjet for teams that value collaborative template building over deep behavioral flows.

Ease of Use

Mailjet feels focused. Because it does fewer things, the interface stays clean and the email editor is pleasant to work in, especially with the collaboration features running. Developers find the API docs clear and the transactional setup straightforward.

Brevo packs more into the screen. Email, SMS, CRM, automation, and landing pages all share the navigation, which is the price of an all-in-one tool. New users sometimes describe it as busy or report a learning curve while they figure out where each feature lives. Once you've mapped it, the payoff is that you rarely have to leave for another tool.

Verdict: Mailjet if you want a tidy, email-only workspace. Brevo if you'll trade some tidiness for one login that covers more channels.

Transactional Email

This is Mailjet's home turf. It offers a reliable SMTP relay and a Send API built for system messages like password resets, order confirmations, and receipts. Combined with the collaborative template editor, engineering and marketing teams can keep transactional templates consistent without emailing files back and forth.

Brevo also does transactional email well, with both SMTP and API access and a shared template library across marketing and transactional sends. For many teams the deciding factor is whether you want transactional and marketing under the same roof as SMS and CRM (Brevo) or paired with strong template collaboration (Mailjet).

Verdict: Mailjet edges ahead for developer-centric transactional setups and template collaboration. Brevo is a capable choice when you want transactional bundled with everything else.

Channels: SMS, CRM, and Beyond

Here the two diverge most.

Brevo is genuinely multichannel. SMS is native and pay-as-you-go, billed per message by destination country, so a campaign to the US costs a fraction of one to the UK. WhatsApp is available, landing pages come in on higher tiers, and light sales/contact tools let small teams track deals next to their campaigns, with advanced sales packages available as add-ons. If consolidating tools is your goal, Brevo delivers on it.

Mailjet stays focused on email. SMS exists within the Sinch family but isn't the native, self-serve marketing feature it is in Brevo, and there's no built-in CRM. That focus is a feature if email is all you need; it's a limit if you want one platform for everything.

Verdict: Brevo, clearly, for anyone who needs SMS, WhatsApp, or a CRM alongside email.

Where Dreamlit Fits

If you're building a product on Supabase or Postgres, there's a third option worth a look: Dreamlit, the truly end-to-end AI email agent.

Instead of clicking through a dashboard to assemble flows, you describe what you want in plain English and Dreamlit builds, sends, and automates the emails. It covers the full stack in one place: auth emails, transactional messages, drip sequences, and marketing broadcasts. Real features include an AI workflow chat, broadcast and recurring workflows, brand kits, managed unsubscribes with automatic suppression, analytics, and a Dreamlit MCP server. Integrations are built around Supabase Auth triggers and a Lovable Cloud to Supabase exporter, which makes it a natural fit for vibe-coded apps from tools like Lovable and Bolt.

The honest caveats: Dreamlit is newer than both Mailjet and Brevo, it's built specifically around Supabase and Postgres rather than as a general developer SMTP or REST API, and it's email-first. It supports internal Slack notifications, but there's no SMS, no WhatsApp, no CRM, and no landing pages. So if Brevo's multichannel bundle is exactly what you came for, Dreamlit isn't a one-to-one swap. But if your stack is Supabase and you want email automation that you can describe in a sentence rather than configure across tabs, it's the most direct path. See Dreamlit pricing for current plans.

The Verdict by Use Case

Choose Mailjet if you're a developer or product team that wants clean transactional email, real-time collaboration on templates, and EU data hosting, and you don't need SMS or a CRM. It's the tidier, more focused tool, and its monthly volume tiers work well for steady daily sending.

Choose Brevo if you're a small or midsize business that wants email, SMS, light CRM, and automation under one login, and you have a large contact list you email occasionally. Its send-volume pricing can reward big lists, but validate the contact caps, and the bundled channels save you from buying separate tools. Just plan to be on the Standard tier to unlock automation. For more on Brevo's positioning, see our Mailchimp vs Brevo comparison and our roundup of the best Brevo alternatives.

Consider Dreamlit if your app runs on Supabase and you'd rather describe your emails in plain English than build them by hand, as long as you do not need SMS, WhatsApp, landing pages, or a CRM.

Both Mailjet and Brevo are solid, mature platforms. The right pick is the one that matches how you send: Mailjet for focused, developer-friendly email, Brevo for the all-in-one SMB bundle. Match the tool to the job and either one will serve you well.

Frequently asked questions

Is Mailjet or Brevo cheaper?

It depends on volume and contacts. Mailjet's free plan caps at 6,000 emails a month with a 200/day sending limit, and paid plans start around $9/month (Starter, 8,000 emails), with Essential at about $17/month for 15,000 emails. Brevo's free plan allows 300 emails per day with up to 100,000 contacts stored, and paid email plans start near $9/month (Starter, 5,000 emails). Brevo's send-based pricing tends to win for big contact lists you email infrequently; Mailjet can be cheaper at steady mid-volume sends. Pricing is current as of 2026 and changes often; confirm current numbers on each provider's site.

Who owns Mailjet and Brevo?

Mailjet is owned by Sinch, the Swedish communications company. Sinch acquired Pathwire, the parent of both Mailjet and Mailgun, in a deal that closed in December 2021, which makes Mailjet a sibling of Mailgun under the same parent. Brevo was formerly known as Sendinblue and rebranded to Brevo in May 2023; it's an independent company headquartered in Paris.

Does Mailjet support SMS?

Mailjet itself is email-focused. SMS is handled through its parent company Sinch rather than as a native, self-serve feature inside the Mailjet marketing dashboard the way it is in Brevo. If multichannel SMS in one interface matters to you, Brevo is the more direct fit.

Does Brevo include a CRM?

Yes, Brevo includes light sales/contact tools and CRM-style workflows, with more advanced sales features available through packages or add-ons. It isn't a replacement for Salesforce or HubSpot, but for small teams it can remove one more subscription from the stack.

Is Mailjet good for transactional email?

Yes. Mailjet has a long history with transactional email through its SMTP relay and Send API, and developers use it for password resets, receipts, and other system messages. Brevo also offers transactional email via SMTP and API. Both can do the job; Mailjet's developer roots and template collaboration are a draw for engineering teams.

Which has better deliverability, Mailjet or Brevo?

Both maintain competitive deliverability when you authenticate your domain with SPF, DKIM, and DMARC and keep your lists clean. Neither has a decisive, consistent edge across every audit. Deliverability depends far more on your sending practices and list hygiene than on the platform name. See our deliverability guide for the setup that matters most.

Where does Dreamlit fit against Mailjet and Brevo?

Dreamlit is an AI-native email agent built for Supabase and Postgres apps. You describe what you want in plain English and it builds and automates auth emails, transactional messages, drip sequences, and broadcasts. It's a strong fit for vibe coders and lean startup teams. The honest caveat: Dreamlit is email-first, with internal Slack notifications supported, but if you need bundled SMS or a CRM like Brevo offers, it isn't a one-to-one replacement.
