Well, I see that #Tutanota is not going to work. Not allowing hot switching between accounts, not having a bridge so I can easily manage my email, and having no way to import my old email so I am not managing mutliple accounts... it's definitely not ready for prime time.
Honestly, between #Protonmail 's buggy mobile client and Tutanota's "we know better than you" approach to mail management, I see why people just give up and use anti-privacy solutions like Google.
