CC
Carbon copy: recipients added in CC receive the message and every recipient can see who else got it.

In practice
Use CC for people who should be kept informed, not for the person who must act: that person goes in To. Replying to all sends your answer to everyone in CC too.
Verification and sending
Every address in CC is a recipient and can bounce. Check addresses before sending to a group.
