An email header is the section of an email that contains important information about the message, such as the sender's email address, the recipient's email address, the subject line, and the date and time the email was sent. It may also include details about the email's routing, like the servers it passed through, which can help trace the message's path. The email header is displayed above the body of the message and is essential for organizing and identifying the email.
