What Does Carbon Copy Mean?
Carbon copy (cc or c.c.) refers to the process of sending a copy of an email message to one or more recipients. It is used in Internet-based email communication systems to simultaneously broadcast or address multiple email addresses. Carbon copy is also known as first carbon copy (first cc) or courtesy copy (cc).
Techopedia Explains Carbon Copy
Inspired by traditional print-based communication, the carbon copy (cc) concept is now applied to email messages. Generally, there is no limit to the number of recipients included in the cc field. Carbon copy works like the "To" element and email body but provides a method of separately addressing primary and secondary contacts.
For example, an email addressed to a manager may be useful for the manager’s team members or related personnel. Thus, the manager’s email address is entered in the "To" field, and other recipients are added to the "CC" field.
Recipients that are carbon copied on email messages have the ability to see and reply to all email addresses in the "CC" and "To" fields.
