You had me until Proton. I bang this drum every so often when it comes up but I’ve had terrible experiences with Proton locking me out of email permanently without warning or explanation in a way that made not just the email address but the accounts linked to it completely unrecoverable.

Don’t play around with email. It’s not communication, it’s critical digital infrastructure - quite possibly your primary key on the internet. The consequences of getting locked out by a faceless provider for reasons you’ll never hear about are probably a lot bigger than you think.
