Please use a personal email. My email is ‘mail’ @ ‘my actual name’. It does not get more personal than that
But you can’t use emails starting with mail@, admin@, support@, info@, main@, etc.
Instead they advised me (3 times) to create a personal email on a service like Yahoo, Outlook, Gmail, Orange, etc
IF you already have an email domain you control.
Calling “acquiring and setting up an email domain and configuring the mail server for wildcards” “basically no extra effort” is a bit disingenuous compared to “solve a captcha for a Gmail account”
