Something like $(hex(hmac(secret_key, service)))@domain could solve that. It would also mean service can't pretend to be another-service@domain when spamming you.

Though who knows, maybe hex addresses will look fake / malicious and trigger a ban anyway.

Zomato refused to change my email to zomato@ (you need to create a support ticket). However, they agreed on otamoz@ (strrev(zomato)).

It's an email, not a "secret", something like 3 or 4 hex (or even better, base58) digits should be more than enough
