Short for
blind carbon copy, a copy of an
e-mail message sent to a recipient without the recipient's address appearing in the message. Most
e-mail clients include two
fields labeled
cc and
bcc. When you enter addresses in the
cc field, the message is copied to those addresses and the cc addresses appear at the top of the e-mail message. When you enter addresses in the
bcc field, however, the addresses do not appear in the message. This is useful if you want to copy a message to many people without each of them seeing who the other recipients are.
