Great Tech Support Was able to open a ticket via chat and have the rep get back to me after the issue had been researched. Didn't have to waste an hour on chat like some other places that won't let you open up a ticket. The rep got back to me quickly with the correct information the first time.

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!

Worst Platform I had upgraded my account for the amount of $30 (50k plan) and i had sended only 500emails and my account has been immediately suspended by them.I had checked with the support and they had told that they will not be able to activate my account.When i asked for the refund they had told they will not be able to provide the refund.I am really very disappointed with the service.So better dont use this platform they will scam you.

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.
