I am now using disroot . I don't care about anonymity or anything as I just wanna use it to connect to my bank, ID and buy/book shit etc. Which all have my phone number, address, name etc anyway so no point in that . I just want the security privacy to be good enough that no one can easily hack it, steal my OTP, inbox etc and I want it to be big and trusted enough that they won't sell it/sell it and go Scott free also gmail asks email or phone number for verification and then brick acc if I don't comply so I'd like to skip those kind of ones . Is disroot enough for my uses ? Also I'd like a free one as I barely use emails like 3 or 4 times a year .
I've been using Fastmail for a few years and I'm quite happy with the service. Being a semi-large organization I expect their security to be OK, but if anyone has comments on that aspect I welcome them.
As for privacy, I always consider e-mail to be a postcard. If I want to encrypt something, I use GPG locally.
Recent convert myself. And now that I've experienced mail, calendar, notes, and file storage all in the same app (android, at least) I can't go back to separate apps.
