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).

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! 🫡

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 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.
