Not recommended First I wanted to connect Google Firebase to import authenticated users to mailersend. But the extension doesn't do anything, contacts still need to be imported manually. After trying to import contacts manually, mailersend tells me to upgrade because I cannot import users without credits. After upgrading, mailersend tells me that the subscription doesn't do anything for new contacts, but I need to buy credits to import them für 250$. After requesting mailersend to refund my money, they told me that they never refund money.

Outstading passion for what they do! From an ecommerce company that has a revenue of near 15M a year, we like to work with partners that have passion for what they do, and that's exactly what MailerSend gave us. The commitment that they put in to fix an issue or to clarify a doubt every time we have one, is outstanding! Keep on going, MailerSend!

Do not recomend !!! DO NOT RECOMEND !!! You need to spend 1 day to get all your mail settings configured. After that they just don't approve an account)))) They took my company information, address and phone number and then disapeared.. My account was not approved: "After careful review, it has been determined that your account does not comply with our terms and community standards. Due to this, your account will not be approved." They don't answer on emails. Thats an awful customer experience in 2023...

Unacceptable attitude towards customers The system itself is not bad at all. The system interface is simple and is quite convenient to use. But ))))), those guys do not respect customers at all. They will close your account and restrict the account log in with no reason. Even if you ask them for additional information and feedback, they won't answer you! They are waiting for stupid clients with a small website and max 1000 recipients. They can not provide you with good deliverability, a lot of emails go to spam, unfortunately. BAD, BAD, BAD!

Great support! Great support! While trying to get my account approved, I was notified that instead, my account had been suspended. I sent an email to ask for clarification since I was sure that I was in compliance with the Terms and Conditions set by MailerSend. Glenn answered me and was helpful, knowledgeable, and kind through the whole process. Finally, we managed to get my account approved, and my address un-blocked.
