In email, CC stands for "carbon copy". It allows the sender to send a copy of the email to someone apart from the recipient in the To field of the email. The CC field is usually located just below the To field in a new message. When using CC, the recipient(s) in the CC list receive a copy of the email for their information only, indicating that no reply is required or expected. The CC field is used to keep someone in the loop or to share the same email with them. However, it is important to use CC judiciously and avoid cluttering the recipients inbox with unnecessary emails.
