That's why I use only one time mails that redirect to my my actual mail. That way I have a extra mail for every service an can disable single address if they get compromised.

What do you use to create and manage all those emails
I use the „Hide my mail“ service from iCloud because im a heavy mac and iPhone user.
But there are other services out there like firefox relay fir example.
I know that these solutions are not the best when it comes to privacy because you have to trust someone.
