I think you’re over blowing this.
A data breach is when someone has your data. Your email address is not your data, it’s just your email address. I think to suggest another poster might use that in some way is a bit far fetched.
Many thousands know my email through work, any one of them could have their computer hacked. I do get some spam like we all do, but in itself another email address added to the bazillions of email addresses available to hackers matters not.
