{{Use mdy dates|date=May 2018}}{{cleanup|reason="Account expiration (inactivity)"
  • The article doesn't explain "Account expiration". Is it (just) a deletion of e-mails, or a removal of the account which means the user would have to re-register if he wants to use it again? Sometimes it's (just) an email expiration, but not an account expiration: One's mails get deleted, but one can still sign-in.

The following tables compare general and technical information for a number of notable webmail providers who offer a web interface in English.
