I can second this. I found their account closure process very aggressive, to the point where I would have to remind myself to sign in to keep my account open. Also the fact that tutanota only send emails between tutanota accounts, of its external, you have to share a key with each user, possibly for each different email.

End result is that my threat model is WAY below this, and their use model becomes a pain for me to use.

Their product seems stellar, branding is clean, and I’ve heard their service is great. If I was a journalist in Russia, reporting on government injustice, it would be my second choice… After proton.

Long Live proton!
