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.

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.

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 !!!

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. 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.
