we have 5,000 customers from the last year. we send first newsletter, a few unsubscribes (as it was first newseltter) and they banned us.paid 45 EUR and not even 1500 emails are sent out. lol.// to double down on their answer: it's nonsense.if you send 1M emails and get 5% unsubscribe, that's fine. but with 300 emails out and 20 people unsubscribe - who cares?
