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.

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...

Not complying... I filled all the fields, but: " 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. "

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.

Worst Platform I had upgraded my account for the amount of $30 (50k plan) and i had sended only 500emails and my account has been immediately suspended by them.I had checked with the support and they had told that they will not be able to activate my account.When i asked for the refund they had told they will not be able to provide the refund.I am really very disappointed with the service.So better dont use this platform they will scam you.
