What is the Cc address field for?

"Cc" stands for carbon copy. In an email it is the field you use to send a copy of the message to people who should be informed but are not the primary recipients.

Quick points:
- Primary purpose: inform secondary recipients (they're kept in the loop).
- Visibility: everyone (To and Cc) can see the Cc list.
- Connotation: Cc usually implies no required action — the main request or task is addressed to those in the To field.
- Reply behavior: Cc recipients receive replies if someone uses “Reply All.”
- Privacy: use Bcc to hide addresses from other recipients or when emailing large lists.
- Etiquette: don’t overuse Cc (avoids clutter); don’t Cc to shame or micromanage; put people in To if you expect them to act.

(Technical note: RFC email headers include a Cc: field that mail clients use to show these recipients.)
