If you own a domain you should maintain forwarders (email address aliases) for your addresses in the public domain record and direct them anywhere necessary. People tend to mistakenly sign up for “Privacy Protection” from their registrar because we all value privacy, right? Privacy is a good thing, who wouldn’t embrace it?
However, what most of us really want in regard to our domain registration is protection from spam. We can quickly direct a forwarder anywhere temporarily or permanently, direct it to as many people as needed to keep everyone in the loop, and change it in an instant if it starts getting spam.
I would only recommend the privacy protection to someone who would like to hide their ownership/identity from others. Spam protection is best done with a disposable forwarder.
