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.

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).

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.

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.

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! 🫡
