cc → Carbon Copy bcc → Blind Carbon Copy cc is a way to send copies of an email to other people. Just like cc, bcc is a way of sending copies of an email to other people. The difference between the two is that, while you can see a list of recipients when cc is used, that's not the case with bcc. It's called blind carbon copy because the other recipients won't be able to see that someone else has been sent a copy of the email.
