What Is Email Masking? A Complete Guide
Email masking is a privacy technique that hides your real email address behind disposable addresses called 'masks'.
Email Masking Definition
Email masking is a privacy technique where you use unique, disposable email addresses (called "masks") instead of your real email. Emails sent to a mask are forwarded to your real inbox, but the sender never sees your actual address.
