Trying to leave gmail because they are evil.
Folks had said protonmail, but it doesn't work with the native IOs mail app, so it's out. I need to sync a bunch of email accounts in one location, so I need to use the iPhone mail app to pull them all together.
I was thinking about using this one in addition to what I currently use (which isn't gmail): https://runbox.com/
I haven't done a bunch of research on them, don't know their politics (or if they have any), but they don't require a phone number (it's optional), and they do IMAP and POP, which is what I needed that protonmail doesn't offer. It says: "Access via Web, POP, IMAP, SMTP, and WAP - Access your email securely using the Runbox Webmail or an email client on a computer or mobile device."
