Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 3 of the 11 other email sending services we grade
Mailjet, part of Sinch, sends transactional email through a REST API or SMTP relay and marketing campaigns through a drag-and-drop editor, both from one account and one plan. Plans are priced by emails sent a month rather than by contacts stored, with EU-based data centers. A free plan sends 6,000 emails a month, up to 200 a day.
To get you started, here are 9 things to know about Mailjet, taken from its own pages and our grades.
Judged on how fast a developer sends a first email: API keys and SMTP details come with the free plan, once your domain is set up.
- 1
Best for app email and newsletters on one plan
It makes sense if you'll use the campaign side too.
- 2
Paid plans start at $8.10 a month
As its pricing page puts it: $8.10 per month for 8,000 emails, billed annually ($9 billed monthly).
- 3
There is a free plan
6,000 emails a month, limited to 200 a day, 1,000 contacts, the API, SMTP relay, webhooks and the email editor. No credit card needed.
- 4
It runs on Web
Web.
- 5
Send API and SMTP relay
Send password resets, receipts and other app email through a REST API or SMTP relay, with templates that take per-recipient variables.
- 6
Parse API for inbound email
Turns incoming emails into data your app can act on, alongside real-time webhooks for deliveries, opens, clicks and bounces.
- 7
Campaign editor and MJML
A drag-and-drop editor with templates for newsletters, plus MJML, a markup language for coding responsive emails.
- 8
A 2.4 GPA, above 3 of 11
That is against the other email sending services we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Mailjet you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for app email and newsletters on one plan
Mailjet puts app email and marketing campaigns on the same plan: an API and SMTP relay for receipts and resets, and a drag-and-drop editor for newsletters, with data kept in the EU. 50,000 emails is $40 a month on Essential, 10% less paid yearly, which is dearer than sending-only rivals. It makes sense if you'll use the campaign side too.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Graded on 50,000 emails a month: Essential is $40 at that volume, 10% less paid yearly, toward the dear end of this category. But the same plan covers campaigns too, with unlimited contacts and segments, and 50,000 is as far as Essential goes. |
| Free plan and trial | C | Free for good, no card: 6,000 emails a month with the API, SMTP and webhooks, the most of any free plan here. But it's capped at 200 a day, and online support only lasts the first month. |
| Features | B | API and SMTP sending, a parse API for inbound email, webhooks, templates with variables, a campaign editor with MJML, validation and inbox previews, and automations on Premium. It covers the sending job and then some. |
| Ease of use | C | Judged on how fast a developer sends a first email: API keys and SMTP details come with the free plan, once your domain is set up. No rating on record. The campaign side adds an editor and lists to learn, if you use it. |
| Platforms and integrations | B | Web, with an API and SMTP relay, plus WordPress, WooCommerce, Shopify, HubSpot, Google Cloud and Sinch Engage. No desktop or phone app, so B is the top. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Mailjet is for
- Great if you want receipts and newsletters sent from one account on one plan
- Handy when your data has to stay in the EU
- Good for side projects that fit in 200 emails a day, which is free
Who it is not for
- Pricey if you only send app email, as you pay for campaign tools you won't touch
- Tight if you pass 50,000 emails a month, where Essential stops and Premium takes over
- Not for you if you need a dedicated IP below 100,000 emails a month
Good to know
Good for
- Teams sending app email and newsletters from one account
- European businesses that want data kept in the EU
- Senders with large lists who email them rarely
Worth knowing
- There are no separate sending-only plans: the same plans cover API sending and marketing campaigns, with marketing features unlocked by tier.
- The free plan caps sending at 200 emails a day and offers online support only in the first month.
- Essential tops out at 50,000 emails a month; higher volumes need Premium, which is $499 a month at 500,000.
- A dedicated IP is available on Premium only from the 100,000-email plan, on request.

Its grades against its category, and whether to keep it or make your own
3/11
Other email sending services it is graded above
Mailjet's GPA of 2.4 is higher than 3 of the 11 other email sending services we grade, and level with 2.
It stands best on features (B, above 2 of 11) and worst on ease of use (C, above 0).
Its paid plans start at $8.10 a month, against a middle price of $15 for the category: 1 of the 10 others that charge start lower.
On features, ease of use and platforms it scores 2.7 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Mailjet you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 6 of the 11 other email sending services grade higher. It costs $97.20 a year.
What you could not
- Mail servers with a good name among inbox providers.
- Newsletters sent to thousands of people that still reach the inbox.
- Email sent in volume that still reaches the inbox.
- Checking that an address exists without writing to it.
- It plugs into other products, WordPress, WooCommerce and Shopify among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Mailjet’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
