In my experience only Yahoo and Aol have hard phone number requirement. Gmail you can get away without a number sometimes but the exact circumstances needed aren't clear. Microsoft and Proton only require verification email, and I'm not sure that it's a hard requirement for Proton. Tuta and cock.li don't require anything.

a way of only letting the recipient (and not the email provider) see the content of emails with asymmetric cryptography, you can also use it to guarantee you (the sender) are who you claim you are, or both at once
