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.

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 service and support Powerfull and very well documented tools : i'm not a pro coder, just need a trusty email service for my business and found no problem configuring my domain dns to start and implementing their API and webhooks in my webapp. Really great and fast support.

I have tested several others and I… I have tested several others and I found this to be the quickest and easy to set up as with the DNS records, get verified to increase limit. So far works great for our newly started company as we need service we can afford as we grow. Time will tell from now but looking at their roadmap looks like they are here to stay.

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).
