I've tried mailchimp and constantcontact so far, but both banned me before I could send out a single email, and refused to give out any information. They didn't say I did anything wrong, just that they refuse to do business with me. At first Constant Contact claimed I was banned because I used a VPN while signing up and suggested I create a new account, but the new account was also banned by what I was told was the Compliance team.
Everyone on my list opted in, this is not spammy content, so I don't understand why nobody wants to do business with me.
Is there a simple service that doesn't have any of this nonsense?
