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
This is exactly what I do. When I start getting a bunch of spam addressed to Walmart@[my domain] I can blanket filter that straight into spam because I know Walmart sold my info.
