Use it when you're sending an email to more then one person and you don't want the other people too see everyone else that you're sending it too. E.g.
To: Bob
CC (carbon copy):Joy
BCC: Fred
BCC: Kim
Bob can see that the email was sent to Joy, but no one else.
Joy can see that the email was sent to Bob, but no one else.
Fred can see that the email was sent to Bob and Joy but doesn't know that it was sent to Kim.
Kim can see that the email was sent to Bob and Joy but doesn't know that it was sent to Fred. BCC stands for Blind Carbon Copy. Any email address that you put in this section will be invisible to anyone else who receives the email. BCC is very helpful if you want to send an email to a large list of people and you don't want them all to see who else is receiving the email. Another use: I want friend A to see what I am sending to friend B but I don't want friend B to know that friend A can see the message. Therefore I would put friend B in the "To:" section and friend A in the "BCC:"section.

Use the "bc" or "bcc" feature otherwise known as blind copy (you have the options of using "to", "cc" (carbon-copy), or bcc (blind copy or blind carbon copy) when sending emails. People will only see that the email was sent to "undisclosed recipients" if you use bc or bcc.
BCC is the same as CC, except that the BCC field isn't public. An email sent to you via BCC will look as if it was sent normally and magically ended up in your inbox. This is handy for mailing lists, as you could send an email to yourself or nobody and have all of the recipients in the BCC field, protecting their privacy.
