"Avoid at all costs"
What do you like best about Mailjet?

When the service works and no human interaction is required, the service does work. Despite the dashboard being very slow.

What do you dislike about Mailjet?

The support is completely unacceptable. We have a plan with paid support and send over 200k emails per month. Tickets go unanswered for extended periods of time and responses are often canned and not relevant. Priority tickets are almost treated with disdain. You do not have to look far online to find a wide selection of similar reviews. Do not make the same mistake as us, buyer beware.

What problems is Mailjet solving and how is that benefiting you?

Mailjet was supposed to be a convenient mail service for our notification emails. We cannot recommend any benefits.

"DISABLE sending limit on master account!!!"
What do you like best about Mailjet?

Price is low but customer service is low either. They don't even read your messages but answer with templates

What do you dislike about Mailjet?

Ticket #1456044 • Status: Opened • Creation date: 12/01/2020, 7:03 PM Our master's account API key was issued by a third-party user for spam. We changed our passwords and updated our API keys. Now we need to disable the sending limit. And you know what? They ask us where did we get those emails? WE WERE HACKED! I DO NOT KNOW!!! Do you read my messages? We were hacked! Someone used our API key to send spam emails. How come I know where did hackers get those emails?! I will close my account as soon as possible!!!

What problems is Mailjet solving and how is that benefiting you?

I was trying to send marketing campaign emails and transactional emails but mailjet just can't make it

"No customer support at all"
What do you like best about Mailjet?

Price but end of the day your email will all go to spam because of their poor SPF

What do you dislike about Mailjet?

No customer support at all. Waited 4 days for an answer and they don't ever read my question properly, than since that 3 days goes and still no answers.. Meanwhile all mails went to spam-box and my domain name is dead... Thanks to their SPF that isn't compatible with Google Domain. Don't think of using them... MAY 2020

What problems is Mailjet solving and how is that benefiting you?

No they didn't and i lost my domain name and 30000 mails... waste all my money!!!

"Basically, stole my money"
What do you like best about Mailjet?

Cheap, relatively easy to set up and use

What do you dislike about Mailjet?

Transactional only service (which is fine, but I was new to this and they could have been clearer), Horrible customer service

What problems is Mailjet solving and how is that benefiting you?

Was trying to do some email marketing. I did not realize the difference between transactional emails and cold emails. They promptly shut down my use. Again, that is fine...learning curve for me. And they did not refund the payment to me. Again, fine, cost of knowledge. My real problem with them is that I sent them an additional $50 from Paypal, which they accept. It never appeared on my account and they say they never received despite my giving them all of the transaction details. They refuse to acknowledge the payment or give me a refund. Their customer service was slow, demeaning, and utterly useless. How does the "accounting team" not find a transaction after giving them every last detail of the transaction? I wonder if they are actually malicious.

"BE CAREFUL! They charge credit card and don't offer the services"
What do you like best about Mailjet?

Nothing, not tested, they cancelled before use and charged me.

What do you dislike about Mailjet?

They blocked my account without any reason, and after that, they charged my credit card for first time. Incredible! They're scammers, be careful and try to use another one email service. Also I'm asking support and they never answer!

What problems is Mailjet solving and how is that benefiting you?

They charge credit card without activate the account.

"They treat their paying customers like crap"
What do you like best about Mailjet?

it actually works when they let you use it.

What do you dislike about Mailjet?

another nazi like email company that will block your account randomly for no reason specified even if you're just sending transactional emails to your own customers.

What problems is Mailjet solving and how is that benefiting you?

We were 200€ per month, sending stats were absolutely fine, except for the last email campaign to our own Customers that got blocked by Mailjet when it went through perfectly and with zero complaints with Getresponse. They blocked our account instantly leaving all our internet businesses without transactional emails and after reviewing our account they now say our business is illegal. (business has been running since 2012 and is the #1 gaming product on Clickbank the biggest digital retailer in the World) This is not how you treat a customer. Avoid this company at all costs, they do not care about their customers.

"complete waste of money, then they ripped me off for more. "
What do you like best about Mailjet?

nothing at all. none of the emails hit inbox. Then I requested a refund and cancelled, and they billed me the next month.... and refuse to refund that month! Unbelievable. French company that doesn't care about customer satisfaction.

What do you dislike about Mailjet?

Mailjet service does not work... no emails I sent were received. Then after I cancel and request a refund they continued billing me and ignored my ticket... Then agreed I was due a refund and 2 months later they wont send it or respond. SCAMMERS!

What problems is Mailjet solving and how is that benefiting you?

no benefit. I was doing email marketing.

"Terrible Service Don't do it!"
What do you like best about Mailjet?

On the surface the service seems fine, but it's not.

What do you dislike about Mailjet?

Clearly they do not have the servers to deliver the service. Their system "pre-blocks" any email addresses that the flawed system flags as blocked. They then use this as an excuse to block many more emails. They then use that as an excuse to slow down their service. Once in that state, you have the task of "proving" that your client emails are appropriate and correct (ambiguous process at best, you are simply at the whim of some support person). Support is slow to say the least. My delivered stats were to say the least world class but they did not deliver many of the emails to my service. I asked for my money back and they refused to return my money and the requested that they could maybe try to send my emails again if I paid another month. Sleazy. French company with no ties to the US, obviously a back office play from some poorly run joker with an Smtp Service. I wasted hours setting put the service based upon their crappy upload system.

What problems is Mailjet solving and how is that benefiting you?

Poor service COMPLETE WASTE OF YOUR TIME!!! DO NOT USE THIS SERVICE.

"Would never use again"
What do you like best about Mailjet?

Waste of time..Would never use again. Only sent out about half of my contact list and took over 9 hours to send 480 emails. Bounces any Apple email addresses (me or mac.com)

What do you dislike about Mailjet?

Process of activation is worst. . Customer support does not address why all emails weren't sent and why it is so slow

What problems is Mailjet solving and how is that benefiting you?

Very worst support team
