To people mentioning public shaming. I had a mailing list with them removed with all contacts lost and account banned without even notifying me. Customer support indeed responded, but with something like your account was banned because you are involved into cryptocurrencies (i had hashcash.io - no selling or buying of crypto is even close) and we completely wiped all your data.
Only after a hint about possible public shaming, someone sent me data dump with all the emails and names. So they lied in the first response (all data is wiped and unrecoverable) and only responded to a threat.

Since then I am using Mautic and own SMTP server.
