Best for teams that want marketing campaigns and app email from one account, priced by emails sent
Facts checked November 4, 2026 · First written by Mutuo Mbilla
The short answer
Mailjet suits a small business or SaaS team where marketers build newsletters in a drag-and-drop editor and developers send app email through the API or SMTP relay from the same account. It charges by emails sent, and from Essential up you can store unlimited contacts, which helps if you have a large list you email rarely. Automations and landing pages only arrive on Premium, from $29 a month, and the free plan stops at 200 emails a day. Its contact pages don't spell out support channels by plan.
Choose it if
- Your developers need an email API, SMTP relay and webhooks and your marketers want a drag-and-drop editor, in one account
- You have a large list but send a few campaigns a month, so paying by email volume with unlimited contacts costs less than paying per contact
- Several people edit the same email and you want them working on it at once with shared version history
- You need support in French, German or Spanish as well as English
- You manage several senders and want subaccounts, up to 20 on Premium, to keep their reputations and reports apart
Skip it if
- You need welcome series or other automations on a small budget: automations start on Premium at $29 a month
- You want to send a whole newsletter free in one go; the free plan allows 200 emails a day and 1,000 contacts
- You want a website, blog or digital product sales alongside your email, which MailerLite includes
- You need SMS campaigns; Mailjet's features page describes none
- You only send app email from code and want the deeper developer tools of Mailgun, its sister product
Main features
Drag-and-drop editor with live collaboration
Build responsive emails from blocks, and from Starter up keep your brand assets in a brand kit. Several teammates can edit the same email at once, with shared version control.
Email API, SMTP relay and webhooks
Every plan, including Free, can send app email through the API or SMTP relay. The Event API posts opens, clicks, bounces and blocks to your webhook as they happen.
Segmentation and preference center
From Essential, you filter contacts by behavior, location or engagement for each campaign. A preference center lets subscribers choose the topics and frequency they want.
Automations
Premium and Custom plans send workflows triggered by what contacts do, such as a welcome series after sign-up.
A/B testing
Test subject lines, images or content against each other and send the version that performs better.
Landing pages and forms
Every plan has a form builder for sign-ups. Premium adds landing pages built from templates or your own design.
Address validation and inbox previews
Essential includes 500 address validations and 500 email previews a month, so you can clean a list and see how an email renders before you send. Premium raises previews to 2,000 a month.
Subaccounts and roles
Subaccounts keep the reputation, activity and reports of different senders apart: one on Starter and Essential, up to 20 on Premium. Premium also adds team roles and permissions.
AI writing help
From Essential, an AI email generator drafts content for you to edit. The site also lists AI segmentation and an MCP server, without detail on how they work.
