I have been migrating one of my smaller email accounts away from Google for the last few months. It isn’t a lot of work, but I have been taking my time in moving all of accounts I could find to use a different email address. Although Proton has come under scrutiny for handing over user data that should have be encrypted, I decided to stick with Protonmail for now. I have a paid account, so it is better to use what I have paid for. I have also created an email account with murena.io but I would be wary of swtiching to any .io domains since usage of it will change soon.
