I'm all for options, to be honest. What ideally I'd like is some sort of good encrypted email based in some safe European country, which can achieve decent Android integration. Proton apps are pretty useless to that effect (lack of offline basic functionalities, the calendar app isn't even an android calendar provider). I'm not too hard in moving around my emails, since for the last few years I've been giving my email @duck.com which actually ends up sending to my final email after some tracking cleaning. Changing email provider would entail only updating my @duck.com destination.
Following up...Yeah, why not Startmail or Disroot? Startmail seems to offer more bang for the buck than Mailbox. I'm not sure how many aliases you get if you get a paid plan in disroot.
EDIT: I...misread. Startmail offers half-priced plan the first year, then goes ahead and doubles it, getting pricier than Proton, Mailbox and about everyone else I think.
Thanks I really appreciate elaborated comments about both. I think I'm going to skip the Tuta encryption for now. While it has a way of keeping it encrypted for the destination, it involves the final user having to click some links in order to open the encrypted mail. I mean...I think most of the people I'd write to would hate having to do extra steps just to see an email I wrote. So I guess I'd have to stick to unencripted, and then the advantage is kinda lost. I'd like a fully encrypted mailbox, yeah, but not at the cost of making it incompatible with any other app or email standards. I guess I didn't have a great experience with Proton apps for Android.
Don't take me wrong, I'd love to have a fully encrypted mailbox, but not by making it all cumbersome.
