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.

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.

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.

They take over a week to respond, leaving you completely stranded.

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

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

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

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.)

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.

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

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.

The multi-editing options are a joke, and there is no way you can send emails to some contacts in a list instead of all.

Simple email builder and reliable delivery rates.

Free tier doesn't give you enough features to  try to determine if this is the right email marketing service for you.

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!

I always come away both happy and boosted in info.
