I really like Runbox. Nothing particularity fancy, just pure standards compliant email, with excellent reputation, for a very low cost. They have a “drive” too.

There’s also mailbox.org, tuta, the upcoming “thunder mail”, proton, fast mail, probably your domain provider or VPS provider offers email as an add on. Consider paying for a email and a domain. It can be as low as $30 a year, and you become the customer instead of the product. Owning your identity.
