I use neither email (for years now, a blessing!) nor have my own phone number (VOIP outbound, only). Anything requiring either gets a burner.email or my numeric pager.
A recent civil court action requested both of these obsolete (to me) technologies, and the judge's clerk required that I sign an attestation upon leaving them unanswerable.
Court records are public in my jurisdiction, and I choose to be "unreachable."
