What Mailjet is

Mailjet, owned by Sinch, is an email marketing and transactional email platform aimed at developers and marketing teams that need both campaign sending and API-based transactional delivery in one account. It offers a collaborative drag-and-drop editor that lets multiple team members comment and edit templates in real time.

The platform splits cleanly between marketing campaigns, with automation workflows and segmentation, and transactional email sent via SMTP relay or REST API for things like password resets and order confirmations. Mailjet provides detailed real-time analytics, including geotracking of opens, and subaccount management for agencies handling multiple clients.

It sits in the email marketing & esps part of an email stack - campaign, lifecycle and transactional sending platforms. In practice it is the right pick when your priority is: teams running marketing, lifecycle or transactional email.

What it does well

The capabilities teams rely on most are campaign and automation builder, segmentation and audience management, delivery and engagement reporting. Taken together these cover the day-to-day work in this category, and they are the features worth testing during a trial rather than reading about.

The real-time collaborative email editor is unusual among ESPs and useful for agencies or marketing teams reviewing templates together, and having both transactional API and marketing campaigns in one account simplifies billing for dev-and-marketing teams.

In real use the strongest points people report are one place for audience, content and sending; established deliverability infrastructure.

Pricing tiers

Mailjet is a free trial product. Free plan with a daily send cap; paid plans scale by monthly email volume, with separate pricing tracks for marketing sends versus transactional API volume.

Pricing pages move often, so confirm the current figures with the vendor before you budget. The number worth modelling is not the licence fee on its own but the cost per delivered email once bounces, suppressed contacts and spam-foldered sends are taken out.

Ideal customer profile

• Best fit: Teams running marketing, lifecycle or transactional email.
• Where it sits in the stack: Email marketing & ESPs - campaign, lifecycle and transactional sending platforms.
• Budget profile: Free trial - suited to teams comfortable with this commercial model.
• Probably not for you if: shared sending infrastructure means neighbours affect reputation would block your team.

What it connects to

Mailjet is commonly wired into WooCommerce, Magento, PrestaShop, Salesforce, Zapier, WordPress, Node.js/PHP/Python SDKs and Adobe Commerce. Check that the specific objects and events you rely on are covered, not just that a logo appears on the integrations page - shallow connectors are a frequent source of rework.

Where it falls short

No tool in this space is complete on its own. With Mailjet the trade-offs to plan around are shared sending infrastructure means neighbours affect reputation; platform reporting rarely shows true inbox placement. None of these are reasons to avoid it - they are the gaps another layer of your stack needs to fill.

Advanced marketing automation and segmentation are less developed than dedicated marketing platforms, so teams needing complex lifecycle journeys may find the automation builder basic.

A useful test before committing: send a real campaign through your intended setup, then check where it actually lands across Gmail, Outlook, Yahoo and your customers' corporate filters. Tooling that looks identical on a feature list often behaves very differently once reputation and authentication are involved.

Works alongside Warmy

Yes - warm-up, placement, DMARC

How it fits a deliverability stack

Deliverability is decided by four things: the reputation of the sending domain and mailbox, the quality of the list, correct SPF, DKIM and DMARC authentication, and proof of where mail actually lands. Mailjet covers part of that picture. The mistake most teams make is buying four separate products for those four jobs and still having no single place that tells them whether the last campaign reached the inbox.

Warmy runs warm-up, inbox placement testing, email verification and DMARC monitoring as one platform, which is why Mailjet usually sits alongside it rather than against it: it keeps doing what it is good at, while reputation, placement and authentication are handled in one loop.

Mailjet offers dedicated IP options for higher-volume senders and provides deliverability guidance, but new senders are responsible for their own warm-up ramp unless they buy premium support.
