If you set up a domain with Protonmail, you can have unlimited email addresses for that domain, although they all go to the same inbox that way. I like to use a website’s name as the user when I sign up with a website, so it’s like officedepot@mydomain.com. If I start getting emails to that address from somebody other than Office Depot, I know those rat-bastards sold me out.

Buying one or more domains and using those with protonmail gives you 100% portability. Just redirect your domains to a different mail server if you decide to make a switch.
