Quickness and deliverability Mailersend is one of the best mass mail send in the current time. We are on the developing stage, and we put on competition almost 10 mass mail ESP, where we need test and to be sure that our transactional mails don't end up into our clients Spam box, or "Promotions" tab for google.. Mailersend was the winner, the second a client register into our system instantaneously the mail is in our clients Inbox (a lots of ESP endup into Promotion tab when it comes to google). I would recommand Mailersend for any one who wants a reliable, sure solution for mass mail sending. Also Mailsersend has one of the bets free plan offer in the market, over 12.000 mail/month, it is a must for a business to automate their mail sending machinery to send/try/experiment with that amount of mails/month after that upgrade to a paid plan (I would say most ESP average is 3000 mail/months which is not that much for tests).

Painful experience and horrible services This website's really painful to navigate and its services are the worst I've ever seen in my life. I'll just give an example but I've plenty like this one: I tried setting up an email address for my domain name like 10 times but it always failed without any further explanations even though I'm doing exactly what is asked. They've lost a great client today, bye bye mail sender! 🫡

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.

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!

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.
