6 Best Mailjet Alternatives Tested in 2026

Last verified Aug 27, 2026

On 9 September 2026 Mailjet raised its prices for the first time in two years, and changed nothing else. The Essential plan at 15,000 emails moved from $17 to $19 a month, about 12 percent, and the vendor’s own notice is explicit that there are “no changes to your current plan, included features, packaging, or feature entitlements”. You are paying more for exactly what you had.

We priced and scored 6 alternatives against Mailjet, ranked by our own review score, and matched each to the specific kind of Mailjet user it wins for. This is not a “top 50” listicle. Mailjet sends competently; what it scores badly on is everything that happens after you press send, and that is what this page is about.

Why look for a Mailjet alternative in 2026

Because the price went up in the two categories where Mailjet scores worst, and nothing came with it.

Our review puts Mailjet at 6.1 overall. Deliverability 7.5 and API 7.5 are respectable: the sending engine works and the developer surface is credible. Support scores 4.5 and automation 4.0. Those two numbers are the reason people leave, and they are also the two things a price increase is normally supposed to buy back.

All 6 alternatives below beat Mailjet on support, three of them by more than three points. Four of the six also beat it on automation. The pattern is consistent enough to be worth stating plainly: Mailjet is priced as a marketing platform and scored as a relay.

The 12 percent matters less than what it signals. A vendor that raises prices while explicitly confirming no feature change is telling you where its roadmap is. If you are on the free tier — 6,000 emails a month capped at 200 a day, 1,000 contacts — the increase does not touch you yet, but the same signal applies.

6 Mailjet alternatives at a glance

Ranked by our overall review score. Every platform here has a full SMTPedia review, so every score is a real measurement rather than a number invented for this table.

Scores are our own review scores out of 10, not vendor claims. Deliverability bands come from the same reviews: High is 8.0 and above, Medium 6.0 to 7.9, Low below 6.0. Mailjet scores 7.5, which is Medium. SMTP2GO does publish a free tier, but its limits are not corroborated by a second source, so we do not put a number on it. Prices are list monthly prices.

1. Brevo — the marketing platform Mailjet is priced like

Brevo

Pricing value 8.5 against 5.5, at $9/mo against $19
7.7/10

Better for: the team that bought Mailjet expecting a marketing platform

Brevo covers the same ground — API, SMTP relay, campaigns, SMS — and adds a CRM, at $9/mo for 5,000 emails against Mailjet’s $19 for 15,000. It scores higher in four of our six categories and ties on deliverability. Its free tier carries up to 100,000 contacts at 300 emails a day, against Mailjet’s 200.

CategoryMailjetBrevo
Pricing value5.58.5
Support4.58.0
API and MCP7.58.5
Automation4.06.0
Deliverability7.57.5

What you give up: the inbox stays where it is. Deliverability is level at 7.5, so if placement is your complaint, Brevo does not answer it — Postmark and SMTP2GO below do. Brevo also puts marketing and transactional in one account, which some teams deliberately keep apart.

2. SMTP2GO — for anyone who has waited on a Mailjet ticket

SMTP2GO

Support 9.0 against 4.5 — the widest gap on this page
7.5/10

Better for: the operator whose real problem is that nobody answers

Support 9.0 against 4.5 is a 4.5-point gap, the largest single-category difference in this comparison, and telephone support is on every paid plan. Deliverability also rises to 8.5 and pricing value to 8.5. If your Mailjet story ends with an unanswered ticket during an incident, this is the specific fix.

Deliverability7.58.5
Pricing value5.58.5

Automation4.03.0

What you give up: the marketing side entirely. Automation falls from 4.0 to 3.0. SMTP2GO is a relay with an excellent support desk, not a campaign tool — if you send newsletters from Mailjet as well as transactional mail, you will need a second platform for them, and that changes the arithmetic.

3. MailerLite — the marketing half, done properly

MailerLite

Deliverability 8.0, automation 6.0 and support 8.0, at the same $19
7.4/10

Better for: the team whose Mailjet volume is campaigns, not API calls

At the identical $19/mo that Mailjet now charges, MailerLite scores higher on deliverability (8.0 against 7.5), automation (6.0 against 4.0), support (8.0 against 4.5) and pricing value (8.0 against 5.5). Same money, four categories better.

CategoryMailjetMailerLite
Support4.58.0
Pricing value5.58.0
Automation4.06.0
Deliverability7.58.0
API and MCP7.56.5

What you give up: the developer surface, and it is the one thing Mailjet is actually good at. API and MCP falls from 7.5 to 6.5 and MCP coverage is partial rather than official. If your application sends through Mailjet’s API rather than a marketer sending campaigns, this is a downgrade, not an upgrade.

4. Resend — for teams that write their own sending code

Resend

API and MCP 9.5 against 7.5, the highest on this page
7.4/10

Better for: the product team whose email lives in the codebase

If Mailjet is a dependency in your application rather than a tool your marketing team opens, the only category that matters is the developer surface, and Resend scores 9.5 against 7.5. Pricing value also rises to 7.5 and support to 7.0. At $20/mo it includes 50,000 emails against Mailjet’s 15,000 at $19.

CategoryMailjetResend

Automation4.05.0
Deliverability7.56.5

What you give up, and it is the wrong direction: deliverability drops from 7.5 to 6.5. Resend is the only platform on this page that lands your mail less reliably than Mailjet does. It is the right move for developer experience and the wrong move for inbox placement — if both matter, Postmark below scores 9.5 on API and 9.0 on deliverability.

5. Postmark — receipts that cannot afford to be late

Postmark

Deliverability 9.0 against 7.5 — the highest we have scored
7.1/10

Better for: transactional mail where a delayed message is a support ticket

Postmark scores 9.0 on deliverability, the highest figure in our index, and 9.5 on API against Mailjet’s 7.5 on both. It reaches that by refusing to be a marketing tool: separate message streams, a narrow acceptable-use policy, and no campaign builder. For password resets and order confirmations that is the correct trade.

CategoryMailjetPostmark
Deliverability7.59.0

What you give up: the marketing half, and some money. Pricing value falls to 5.0 and the overage is $1.80 per thousand, double what Resend and MailerSend charge. Postmark will also decline traffic that Mailjet accepts: if your sending includes anything resembling a bulk campaign, check the policy before you migrate rather than after.

6. MailerSend — the cheapest credible way out

MailerSend

API 9.0 and value 7.5, at $7/mo against $19
7.1/10

Better for: the small sender who wants out of the increase without a project

MailerSend is the budget answer rather than the technical one: $7/mo for 5,000 emails against Mailjet’s $19 for 15,000, with API scoring 9.0 against 7.5, support 7.0 against 4.5 and deliverability level at 7.5. It has a drag-and-drop template editor, which Resend and Postmark do not.

CategoryMailjetMailerSend
API and MCP7.59.0
Pricing value5.57.5
Support4.57.0
Deliverability7.57.5
Automation4.04.0

What you give up: nothing measurable, and that is the catch. Automation stays at 4.0 and deliverability at 7.5: MailerSend is cheaper and better supported, not better at sending. If your complaint about Mailjet is placement rather than price, this move does not address it.

Leaving Mailjet: what transfers and what breaks

A relay is easier to leave than a marketing platform

Mailjet sits in both camps, and which one you are in decides how hard this is. If you send through the SMTP relay or the API, the migration is mostly a credentials change and a redeploy: one to two days on every platform above, and SMTP2GO is a single day because it is a like-for-like relay. If you also run campaigns from Mailjet, add the campaign rebuild, because no destination on this page imports automations.

What transfers: contacts, suppression and bounce lists, and sending history as an export. What does not: templates keep their HTML but lose their editing structure, and anything Mailjet does with its own template language has to be rewritten. Authentication records must be republished for the new sender before the first send, which is the step teams skip and then blame on the new vendor.

One sequencing note specific to leaving on a price change. The increase took effect 9 September 2026; if you are on an annual term you are not paying it yet, which means you have the luxury of running both platforms in parallel for a full send cycle before you cancel. Do that. It costs one month of overlap and it is the only way to compare placement on your own list rather than on our score.

Mailjet alternatives: common questions

How much did Mailjet actually go up?

The Essential plan at 15,000 emails moved from $17 to $19 a month, about 12 percent, effective 9 September 2026. The vendor describes it as its first pricing adjustment in two years and states there are no changes to features, packaging or entitlements. The Starter plan keeps its current pricing, and the annual discount stays at 10 percent.

Which Mailjet alternative is the easiest switch?

SMTP2GO, at about 1 day, because it is a relay replacing a relay: repoint credentials, republish authentication, send. It is also the largest single-category improvement on this page — support 9.0 against 4.5. The catch is that it does not do campaigns, so it is only the easy answer if your Mailjet usage is transactional.

Is there a free Mailjet alternative?

Five of the six. Brevo is the most generous at 300 emails a day with contacts to 100,000. Resend gives 3,000 a month capped at 100 a day, MailerLite 250 subscribers and 2,500 emails, MailerSend 500 emails, Postmark 100. SMTP2GO publishes a free tier whose limits we could not corroborate, so we do not quote a number for it.

Which one actually lands in the inbox?

Postmark, at 9.0, the highest deliverability score in our index, followed by SMTP2GO at 8.5 and MailerLite at 8.0. Mailjet scores 7.5, which is mid-band rather than bad. Note that Resend at 6.5 is the one platform here that scores below Mailjet on this, despite being the best on API.

Should I move if I only use the API?

Then your shortlist is three names, not six. Resend for developer experience (9.5), Postmark for placement (9.0 deliverability and 9.5 API), MailerSend for cost (9.0 API at $7). Brevo and MailerLite are broader platforms whose value is in the marketing side you would not be using.

Is a 12 percent rise worth migrating over?

On its own, rarely. Two days of engineering time costs more than $2 a month. The case is stronger when the increase confirms something you already suspected: support at 4.5 and automation at 4.0 are the two weakest scores in our Mailjet review, and the vendor has stated plainly that neither is changing. Migrate on the scores, not on the 12 percent.
