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).

Horrible Customer Service without Justification Upon attempting to contact their support team, not a single member would respond to assistance. Instead, they responded every time with an email stating, "after careful review, it has been determined that your account does not comply with our terms and community standards. Due to this, your account will not be approved." There is no due reason that our platform does not comply with their Terms of Use and Policies and their denial to refuse service. Here's the timeline. Over the course of multiple attempts of trying to contact support, all the following occurred: - We have not sent a single email through their platform, yet the account was suspended - All domain and subdomain DNS records were verified (ie SPF, DKIM, bounce, return, updates) but the account never was - We did not receive a single email or contact method to a support staff member to verify our domain name - We provided them various forms of social media as they requested, resulting in no change of domain approval status - We provided 3 months of invoices from our existing email service, resulting in no change of domain approval status We did all they requested and they could not even respond to their decision. As a warning to future users, this company appears to bias their customers and decide to service them or not.

Impressive support people I am just testing the suitability of mailer send, but great software is only as good as the support. I ran into a question and given I am currently only on a free account I was amazed to get a response within half an hour which allowed me to continue working. And it was from a human being !!!

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. They suspended our account without any reason Looks like this company is not interested in onboarding new customers. After having us fill out a lengthy form about our business model etc, they just suspended the account. They do not mention what the reasons were. No idea why this happened, despite ours being a legitimate e-commerce business.
