Their support responses felt like a never-ending compliance loop, with repeated requests that are not always realistic for large companies with hundreds of thousands of active customers. If you are a company planning to use Mailjet for high-volume customer communications, especially if your contacts come from an existing contractual customer relationship rather than a simple newsletter checkbox, be very careful.

Slow interface and system lag

70% of reviewers feel negative about Mailjet’s performance and speed. Users report that the web interface is often slow to load, with delays navigating between pages and performing tasks. They mention that the backend can be clunky, requiring excessive clicks and repeated actions before the system responds. Some reviewers say that slow server response times and laggy automation tools make managing large lists or campaigns time-consuming. Many find the navigation confusing and the overall user experience hindered by frequent slowdowns.

Unpredictable account suspensions

Twice, our account was blocked for over a week with ZERO warning. Why?

Blocking an account without notifying the account holder beforehand is an irresponsible practice. If there was a legitimate concern, we should have been informed and given an opportunity to address it rather than being abruptly cut off.

Some mention being charged during suspensions or having difficulties resolving billing and account access issues.

Strict and opaque spam controls

67% of reviewers feel negative about Mailjet’s handling of email spam. Users report that emails are sometimes blocked or marked as spam without clear reasons, making it difficult to understand or resolve issues. They say the process for unblocking addresses is manual and slow, and that blocked or spammed emails are not always easy to identify or manage. Some reviewers mention that legitimate emails are flagged, leading to business risks and account suspensions. Many express frustration with the lack of transparency in spam filtering and email blocking.

Slow and unresponsive support

56% of reviewers feel negative about Mailjet’s customer support. Reviewers indicate that support is often slow to respond, with ticket-based communication leading to long wait times and repetitive exchanges. They say it is difficult to reach a real person, and many feel their issues are not resolved efficiently.

Reliable email delivery and tracking

Senior Marketing Manager

Email delivery is practically guaranteed, and you can track each individual message's progress, receipt, and opening.

85% of reviewers feel positive about Mailjet’s email sending capabilities. Reviewers indicate that the platform reliably delivers both transactional and marketing emails, and they value the ability to track delivery, opens, and clicks. Users appreciate the clear statistics and dashboards, as well as the ease of setting up SMTP or API integrations. They mention that Mailjet helps automate notifications and manage large mailing lists efficiently. Many find the scheduling and template management features useful, and note that the service is suitable for both small and high-volume email needs.

We are not using purchased lists, scraped contacts, or unsolicited third-party marketing campaigns. Despite providing multiple explanations about our business model, customer relationship, data collection process, legal basis, and campaign metrics, Mailjet kept applying restrictive sending limits and repeatedly asked for increasingly specific documentation, including individual proof of consent for specific contacts.

In our experience, Mailjet was not a good fit for enterprise-level customer communication where contacts are collected through real business processes, contracts, customer service interactions, and onboarding workflows.

Our data is top-notch: over 98% deliverability, engagement and click rates far above the industry average, almost no unsubscribes, and nearly zero spam reports.

Human Resources Generalist

I send monthly marketing emails for our engineering company, and Mialjet provides me with everything I need to make them great.

The interface is fairly simple and allows you to create and send campaigns without too much difficulty.

Owner

I use Mailjet for system alerts when it's a pain to get O365 to work.

Title: Extremely frustrating compliance process and sending limits for legitimate business use**

Direct Marketing Coordinator

The slight difference in goals would be the only thing in my mind, I make emails for an attraction and not a sales business.

Manager

The platform feels user-friendly with a drag-and-drop editor that makes it easy to build branded emails quickly.

Pricing is also reasonable compared to some competitors, which can make it attractive for small businesses at first.

Designer

One of the interesting features of this system is that you can send transactions and emails on the same platform.

We are a tiny startup with only 10 employees, and we used Mailjet for 2.5 years.

I spend a few days trying Mailgun and and other email services but they didn't work, the onboarding was difficult and they mostly lack documentation.

At this stage, I haven’t used it long enough to fully test deliverability, reporting, or automations.

I like using Mailjet, but I don't like that some emails are tagged as spam, so I have to check the spam.

Email Marketing Speciliast

From email creation, testing, sending and statistics.

AI is also kinda useless I used very good prompts to generate a template but it wasn't good at all.

Web Developer

Free plan of mailjet is limited in terms of number of mail sending per month

marketing coordinator

I like how you can see a lot of stats based on email.

Mailjet doesn’t care. And if you think support will help?

Good deliverability (emails less likely to land in spam).

I appreciate their marketing insights, and I love the bots vs human metrics!

The template customization options could be a bit more more flexible.

It offers drag and drop features, by which it is easier to user to design and sending mail

Email Marketing Specialist

ease to use - the layouts are good, and very ease to use - but having some basic template would be great

They suspended our account without notice because they suspect spam is being sent.

It's been pretty user-friendly, and the team seems happy to help their users succeed.

I'm still learning how to get the most out of the design module.

The API is okay, they have a good deliverability and it's important for an emailing company.

Yoga teacher, Healer, Homeopath

We signed up for an account in order to send out emails.

sales

would have kept using if customer support helped. But they lost me too much money from not being helpful

Marketing Team Lead

Mailjet is an ideal tool for creating and sending emails marketing campaigns and newsletters.

Digital Marketing Manager

Simple email builder and reliable delivery rates.

Product Manager

We do not store any contacts and we only use this service for transactional emails.

Solid email marketing tool with good automation.

It said the account had been closed for undisclosed reasons. How strange!

The free tier Mailjet offers comes with 200 emails/day, 6000 emails/month. When you upgrade to the essential package, you get up to 50k emails and features like segmentation and email verification for $35/month (10% discount annually.)

I always come away both happy and boosted in info.
