For the Proton people. I learnt about a guy that ended up in a US court and they asked proton for all his emails and the handed them right away, no questions asked.

iCloud Mail. I have a Proton account, but the app takes several seconds to load and show me my messages on my phone and I hate the delay. Plus, as of iOS 17, Mail now autofills email verification codes and delete the email afterwards. Plus Mail is built into Siri and all that jazz, so it sometimes shows possible events that I can add to the calendar. So convenient.

Honestly, gmail for bills and that kinds of stuff. iCloud for personal stuff. I do not really use email that much other than getting spam. I imagine that is true for most people. I do not understand why the privacy community is so obsessed with private email. Are you really using it for stuff that needs to be so private?

proton's honestly a great deal if you're gonna use the VPN and Password managers. nice easy drop-in replacement for Gmail imo, not much point putting a ton of effort into it since email is inherently insecure

Dealers choice on emails imo. Doesn't really matter because you can't verify that they aren't scanning your emails for advertising.

Gmail actually isn't too bad if you use an email forwarder like simple login that kets you pgp encrypt your mail before it gets to google.

gmail because i love google!! nothing to hide, right?

edit: /s

gmail, protonmail and tutanota also i will eventually get a posteo.de account
