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
I do this with my domain and it works great.
Only negative I’ve had is that people with a similar name have ended up signing up for things and misspelling theirs with it ending up on mine.
