In e-mail, the abbreviation CC indicates those who are to receive a copy of a message addressed primarily to another. The list of CCed recipients is visible to all other recipients of the message. An additional BCC (blind carbon copy) field is available for hidden notification; recipients listed in the BCC field receive a copy of the message, but are not shown on any other recipient's copy (including other BCC recipients). It is considered good practice to indicate to the other recipients that a new participant has been added to the list of receivers (e.g. by writing "I have CCed Rudolf Grabner").
In common usage, the To field recipients are the primary audience of the message, CC field recipients are others whom the author wishes to publicly inform of the message, and BCC field recipients are those surreptitiously being informed of the communication.[1] Additionally, an LCC field (for "List Courtesy Copy') is available for e-mail distribution lists that, like BCC, hides the full recipient list but, unlike BCC, alerts recipients that other unnamed members of the list have been included in the distribution.[2]
