FastMail uses US-based servers (hello, NSA!) and is just email (and years ago, they had a five-day outage when I was their customer). ProtonMail encrypts messages between Protonmail users, is Swiss-based so they're protected by Swiss privacy laws, and their servers are located 3000 ft. below the Swiss Alps in a bunker hardened against nuclear attack (just in case anyone worries about that, I guess). :-)
