The scene where Al Pacino gets slapped by a big black guy wearing only a cowboy hat and a jockstrap in Cruising (1980)

If you want free, I’d recommend Protom Mail.

For paid, I really like Mailbox.org and Posteo. They work with IMAP/POP3, CardDAV, and CalDAV

I personally like both Posteo and mailbox.org, but they are paid email services.

You can use them for your email, contacts, calendars, and tasks. On Android, you can use Davx5 to sync them.
