Could you explain what you believe has happened here, as your posting is confusing?
It is fundamentally impossible to hack an email address. That’s just not how an email address works. Accounts can be hacked certainly, and variously are. But not email addresses.
Addresses can be collected and used by spammers and scammers too, but that’s also inevitably going to happen with any replacement email addresses.
And yes, email addresses can be caught in various breaches, but that has no effects on the account. Unless you are reusing passwords, and that re-use would be bad, and that password re-use often becomes a mess. The fix for thst is to not re-use passwords.
This is a user-to-user forum. We’re other users, not Apple, and nobody here has access to your Apple Account.
TL;DR: can you explain what happened with your email address?
