Email header

An email header is a block of metadata attached to every email that contains routing and identification information.

The email header includes fields such as sender, recipient, date, subject, and the path the email took through mail servers. It plays a key role in email authentication and security by allowing recipients and servers to verify the message's origin and detect tampering. Understanding headers helps diagnose deliverability issues and spoofing attempts.
