required help
Required help, Theo kindly called back & has been exceptional. Not only did he help & assistance with my initial queries, but went above & beyond to help on what I was setting out to achieve. Fantastic service & great that I got to speak with someone rather than a robot. Thank you Theo.

AI support weak!
I found AI support for email marketing a bit weak. I think the AI support should be more strong in marketing style. Shorter explanation but more marketing expression would be better.

Worst customer support
Worst customer support, not onboarded the profile even after 2 weeks. Response time slow and minimal explanation.

Hello Steffen, we're truly sorry to hear about your experience so far. Due to the large number of queries received over the past days, it has taken us longer to answer you, please accept our sincere apologies. A support member from our team has taken care of your ticket.
Excellent and human support from Mihael!
My transactional account was blocked due to a technical misunderstanding and a past security issue. Mihael from the support team was incredibly helpful, patient, and professional. He took the time to escalate the issue and understood the situation perfectly. My account was unblocked quickly. Truly "legendary" support, thank you Mihael

Waiting for their approval, now approved
My business validation has not been approved yet, maybe because I'm a small customer. After registration they announce that it'll take a few minutes to get started, I'm stuck at first step and ticket has been open for 24 hours.
Edit: Just got cleared and I can now start developing with Mailjet. It’s good they have compliance in place for new customers, trust is good but support can be more responsive (really good when they get in touch). But I’m now a happy customer!

Unexpected service interruption
The service was interrupted without any notification from your end and I stopped receiving the emails.
Ideally, I would have liked to be informed beforehand.
