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
As a person who ages ago created and single letter (before the @) email address thinking myself clever and efficient… I’m amazed and distressed how many forms have insisted that my email address is invalid.
