I'm always interested in email options that don't require any information, including no telephone number.
And I just ran across this:
https://minitechtips.com/email-without-phone-number/
Which mentions Inbox.lv.
https://login.inbox.lv/signup?go=portal
Any opinions? I had an account on the old Inbox.com, mostly because I liked the simple, sensible name, but I gave it up when it was no longer free.
