Customer service is great Customer service is great; when I needed an email sending platform, MailerSend made it easy for me to accomplish, when I initially thought it was going to involve a lot of knowledge base -- talking to them about my challenges and explaining my specific situation was really helpful toward getting help. I also want to thank the MailerSend Team for their support.

Same as others, account suspended Same as others. Set up an account and configured wait list page to store email addresses and send thank you emails. Got hit by a bot over the Xmas period and account suspended due to high bounce rate. Added extra checks in to make sure email address has valid DNS, RFC compliant and Google ReCaptcha. Have tried multiple times to contact them but have no replies. Will look for a better alternative.

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.

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!

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.
