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!

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!

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.

Horrible support and unjustified… Horrible support and unjustified account suspension although we never sent a single email trough their platform. We tried contacting support trough email two times and they never replied, also they blocked our access to live chat and the only contact option was their regular contact form on site. We tried contacting them again through the contact form and they replied that our account is suspended since it doesn't comply with the ToS ALTHOUGH upon registration I contacted live chat to ask if our use case is okay and they said we are 100% complying with their ToS but then suspend our account regardless. Worst service and customer support I have ever seen.

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.
