I had similar feelings a couple of years ago with regards to my Gmail account. Which is when I signed up for Proton, first free and then went to the lowest tier of subscription. I really like it. Yet, unlike you I have not yet invested the time to make a full switch over to Proton i.e. am still using my gmail which - of course - has been compromised on the darkweb - sigh. I've also toyed with the idea of making an email address just for e.g. newsletter sign-ups (hardly do that anymore though, still...), a friends&family one, an artist one, hmm, I'm sure there could be more, oh, a crypto one. That reminds me, a couple of years ago I wanted to sign up with the Proton email for something crypto, maybe Bittrex? Guess what - Proton Mail wasn't allowed in their country due to its privacy restrictions - yeah... that.
