An
email header includes essential fields used for addressing and categorizing emails:
1.
To: The primary recipient(s) of the email.
2.
Cc (Carbon Copy): Sends a copy of the email to additional recipients.
3.
Bcc (Blind Carbon Copy): Sends a copy of the email to additional recipients without revealing their addresses to others.
Important Key Points:
1. The email header helps in routing the email and specifying recipients.
2. The "Bcc" field maintains privacy by hiding recipients' addresses.
3. Headers may also include technical details like subject, date, and sender's information.
