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
Automailers often have names like that i.e. [email protected] so it may be more about stopping spam or stopping people from using spam email accounts.
That sounds like nonsense.
