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!

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.

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.

Great Tech Support Was able to open a ticket via chat and have the rep get back to me after the issue had been researched. Didn't have to waste an hour on chat like some other places that won't let you open up a ticket. The rep got back to me quickly with the correct information the first time.

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.
