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.

Do not recomend !!! DO NOT RECOMEND !!! You need to spend 1 day to get all your mail settings configured. After that they just don't approve an account)))) They took my company information, address and phone number and then disapeared.. My account was not approved: "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." They don't answer on emails. Thats an awful customer experience in 2023...

Scam- They are letting intruders… Scam- They are letting intruders register services on my domain. I think Google will stop it before it goes too far, but this is NOT enough security for a mailing service anyone would actually want to use.

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.
