content: Did you mean Tutanota, right? I use Gmail mostly for newsletters because I like the filters, it's easier to manage my inbox. Tutanota it's great, but if you sent an email to Gmail/Yahoo etc, it's the time thing as sending that mail from Gmail.. anyways I prefer phoning over emailing, I don't trust my phone provider either, but at least I'm sure that the person to whom I talk will hear me instead of replying after two weeks.
