What made you opt for Fastmail over Protonmail? I'm still on gmail, but I'm interested in switching. Want something that supports calendars too. Only think I'm not sure I can get away from is Android... I really do prefer it to iOS.
The spam-filter is terrible but the support actually answers you.
I chose fastmail over proton or tutanota because they’ve been around longer and charge everyone money. Maybe I’m paranoid but I don’t trust free as in beer very much anywhere. + none of my mails would actually use the encryption.
