Mailjet Review (2026): Features, Pricing, Pros & Cons

Mailjet is one of the more developer-friendly names in email, sitting at the crossroads of marketing campaigns and transactional sending. It's a good fit for teams that need both — a marketing team designing newsletters and a product team firing off receipts and notifications through an API — under one roof. That dual nature is its main distinguishing feature.

What is Mailjet?

Mailjet is an email platform that handles both marketing campaigns and transactional email. On the marketing side you get a drag-and-drop builder, contact lists, segmentation and basic automation. On the developer side you get a robust SMTP relay and API for sending password resets, order confirmations and other system emails reliably. A standout touch is real-time collaboration in the email editor, so multiple people can work on a design together.

Key features

• Drag-and-drop email builder with real-time team collaboration
• Transactional email via a well-documented API and SMTP relay
• Contact management, segmentation and basic automation workflows
• A/B testing and deliverability monitoring tools
• Reusable templates and dynamic content with personalization
• Sub-accounts and role controls suited to larger teams
• Statistics covering opens, clicks and delivery in real time

Pricing

Mailjet prices around the volume of emails you send rather than purely contact count, which suits high-volume and transactional use cases. There's a free plan with a daily and monthly send cap that's useful for small projects and testing, then paid tiers that raise limits and add features like no daily cap, segmentation and dedicated IPs higher up. For teams sending a lot of transactional email, the volume-based model can work out cheaper than contact-based competitors.

Pros and cons

Key pros are the combination of marketing and transactional sending, a developer-friendly API, the collaborative editor and a usable free tier. The volume-based pricing is a plus for some. The downsides are that the marketing automation is fairly basic compared with specialist tools, the interface can feel a little dated in places, and advanced deliverability features sit behind higher tiers. It's a capable generalist rather than a best-in-class campaign tool.

The verdict

Mailjet is a sensible pick for teams that need both newsletters and reliable transactional email in one platform, particularly where developers are involved. The collaboration features and API are genuine strengths. If your focus is sophisticated marketing automation or cutting-edge design, a dedicated platform will go further. But as a flexible, fairly priced bridge between marketing and product email, Mailjet holds up well.
