Since I don’t know what your requirements are, I’m just going to list some “good alternatives” for email that are paid services and have a better focus on privacy/customers:

- Posteo.de

- Runbox

- Mailbox.org

- Mailfence

As a Gmail user, you’re probably not as concerned about five eyes surveillance as some others may be. If that’s true, then add Fastmail into the above mix.
