E-mail term. An acronym for "Blind Carbon Copy". BCC lists addresses to which a message should be sent, but which will not be seen by the recipients. Supported by most e-mail systems, a normal, non-blind "CC" header would be visible to all recipients, thus allowing them to reply to each other as well as to the sender. The addresses listed in a BCC header are not included in the copies of the message sent to the recipients.
