Mailjet Reviews 3,689

I use Mailjet as part of integrating their API into my project, and I would like to highlight the exceptional quality of their customer support. The team responds very quickly to requests, which is particularly valuable when working on time-sensitive technical integrations.

A big thank you to Théo Godre, who was extremely efficient and professional. He understood my problem, guided me step by step, and quickly resolved the issue. His support allowed me to finalise the integration without any friction.

I highly recommend Mailjet for their responsiveness, technical expertise, and quality of support. They offer real added value for any project requiring a reliable emailing solution with excellent support.

Instability and poor technical quality (e.g. frequent login issues, major issues with A/B-testing, HTTPS certificate generation error on landing page), and incompetent support.

support was fast, friendly and reliable. Problems were fixed rapidly.

Théo and the whole Mailjet team were very understanding and offered excellent support; everything was sorted out the same day.

I emailed MailJet and Théo got back to me right away and was able to assist with getting me up to date with my website access and databases so I have no more concerns moving forward. He happens to be a great asset to MailJet and reguardless of my level of understanding of the process he was able to help without judgement. Thanks to you AND especially Théo for the help!!!!

Excellent support from Mailjet. The team was responsive and helpful, quickly resolving my account issue and clearly explaining how to verify and send emails safely. Professional and stress-free experience.

Over the years I've used lots of different email sending providers and I've found Mailjet to be one of the best. It's very easy to use with a simple, straightforward interface and fair transparent pricing that offers excellent value for money. Most importantly our emails get delivered where and when they should and we have great insights into all the data we need.

The initial response was from a representative that wasn't qualified to help, and had to escalate it. The rep that then came back (eventually) apologized for the delay due to a larger than normal number of support queries, and proceeded not to answer the ticket enquiry at all, but asked for more information that would have been very, very obvious just from taking a cursory look at our account.

We were dealing with a tricky SPF alignment issue on Mailjet. Mihael guided us clearly through setting up the correct CNAME for a custom return-path and followed up quickly to verify and configure things on his end.

Even when the issue required some back-and-forth, he stayed professional, efficient, and friendly. The documentation shared made the process much easier.

Appreciated the help Mihael!

Lara and Ajay were quick and supportive in resolving my issue.

Support is understanding and most importantly human. Lara was very helpful and reactive! Thanks again.

Business owners beware. We’ve been using Mailjet for nearly 8 years on their most expensive plans. Every year, 3-4 times, something breaks: sending errors, API downtime, automations stopping, contact imports failing, and more. Each time, our team has to be the one to detect the issue and contact support. The result? Disastrous reactivity (1+ week delays), constant agent turnover, and zero willingness to investigate internal problems. Don’t be tempted by the low prices, it will cost you much more in time and lost revenue due to unstable, unreliable service, no communication about incidents, and nonexistent support even on top-tier plans. We’re now spending several thousand euros to switch ESPs, which I can confidently say will be our best decision after all these years.

Simeon was very kind and efficient providing accurate solutions for my issue.

I received exceptional support from Lara during an important issue with our Mailjet account.
She responded quickly, explained everything clearly, and followed up until the problem was fully resolved.
Great communication, very professional, and genuinely helpful.
Thank you, Lara — outstanding service!

Are you joking. the WORST EXPERIENCE EVER

Good proactive detection of abnormal mailflow, while it wasn't malicious, it was an absurd quantity that was very much unexpected and we have since mitigated.
Mihael was very helpful in getting it figured and sorted out.

Responded quickly to my enquiries. I had multiple enquiries and they were dealt with pretty quickly from the team. The platform itself is also really easy to use.
