Theo once again is the most helpful customer support agent I've ever dealt with! Very quick response time, and always helps me resolve my issues. Is willing to go the extra mile, and even spend time on the phone talking through options. You don't often get this kind of personal service anymore. Thank you Theo!

The free version works completly fine for a simple contact form email sender.

They even provide you a test account different to the main one, so you don't get your prod environment tagged as spam.

The customer service is easy to reach, thanks to multi-canal offering.
And I got Theo from support, very helpful, answering all my questions.

Thank you for the quick answer and availability.

I recently went through Mailjet’s onboarding and domain verification process, and I’m very impressed by the level of support I received from Mihael.

He was consistently responsive, patient, and very clear in guiding me through each step — from domain alignment and authentication to resolving configuration issues and ensuring that my initial sending limits were properly set for testing. His explanations were concise, accurate, and genuinely helpful, especially given that my website was still under active development.

It’s rare to receive support that is both technically knowledgeable and truly considerate, and Mihael delivered exactly that.
Thanks again for the excellent assistance — much appreciated.

The mailjet team is always there when I have questions. Slavena and Mailjet specifically were able to find answers for an issue I encountered and helped greatly. Thank you !

Accurate support and follow-up from Mihael!

I worked with two agents during my contact for support, first, Sree and, second, Lara. Sree, who after initial conversation realized I would be better assisted by another team, transferred my ticket to the more appropriate team. My ticket was picked up by Lara. I worked with Lara to full resolution thereafter. The entire time, communication was professional, friendly, and germane. My support was provided entirely over email asynchronously and I am really pleased with 1) the frequency of updates and 2) being accurately informed on what to expect along the way.

MailJet makes sending bulk emails incredibly easy. It's user-friendly and has the right tools to create attractively designed emails. But its best feature is its support system, even for free accounts. They resolve issues quickly and are always attentive to ensure everything is sorted out. A special thanks to Zoya, who provided excellent and patient assistance.

Theo provided excellent customer service. He was very patient and answered all of my questions. He should be commended.

Someone actually wanted to understand what was happening for me to get the issue, before providing me with template solutions.

Thank you!

Got a good service. recommended

Contacted for an urgent issue, 2 days passed still waiting for a reply

The service is just BAD. Not friendly for the startups. I had to wait 3 days for my support tickets being seen. I was not able to verify my domain because of "unknown error". It is just bad. Search another mailing company.

Update: I requsted account removal because I just wasted my time with your service. You can check Request #3821950 and Request #3822784

Mailjet: What a Great Company!

I was recently searching for a reliable way to send alarm emails from an IoT device, and ChatGPT recommended Mailjet. When I went to sign up, I quickly saw that the platform is really designed for businesses and larger-scale email automation—not a simple once-a-week IoT alert system.

So I reached out to their support team, expecting a form reply… and instead received a thoughtful response from an actual person. After asking a few clarifying questions, they decided my little project was worth supporting.

Thanks to that, I now have a clean, dependable, and easy-to-integrate email notification setup for my IoT device. Very cool—and a little bit of early Santa magic! 🎅

Mailjet offers an email delivery platform with a free plan that is generous for new users and small projects. The key features are available without cost. Their support team handles tickets with care and gives clear guidance.

Mailjet has been a reliable and easy-to-use email service for us. The interface is intuitive, deliverability has been solid, and the automation tools work smoothly. Their support team has also been helpful whenever we needed clarification. Overall, a great experience so far.
