I have a list of email subscribers. I want any one of them to be able to prove they are one of my subscribers without revealing their specific email address. What’s the easiest way to do this today?

Doesn’t this doxx them if I know which priv key I sent them?

You can solve this using public key cryptography. Email your subs with a unique private key. Set up a validator site where they can come prove it against your public key. You can even ensure each key is signed only once and the email associated with it
