Email to, CC, bcc meaning

CC English full name is Carbon Copy (cc);

The BCC English name is Blind carboncopy (Dark cc). 
the difference is that the recipients in the BCC bar can see all the recipient names (TO,CC,BCC), and the recipients in the To and CC columns do not see the name of the BBC's recipient.

E-Mail can have three types of recipients, respectively to, CC (carbon copy) and Bcc (blind carbon copy), respectively, is the recipient, Cc, BCC, in fact, to and CC in terms of permissions are the same, just CC to who is often you are telling him you put the mail to who, Or CC's people have something to do with the subject matter of the email, but he's not the person you wrote the email to, or you want someone who knows it has something to do with your CC, and it's back to them when you get back to them, roughly like this. Specific examples: 1. Someone asked you to do one thing, send an email to who, you write the recipient in to, at the same time cc to the person who asked you to do this, one is to let him know that you did this matter, it also let him know how your content is written; 2. You write an e-mail to a person, and you feel that the matter can let others know, it is also helpful to them, so you put mail C c to others; 3. You write an e-mail to A, this matter and B also has a relationship, you want a back to the e-mail can also be sent to B, so you put this message cc to B (of course, a received email is reply can only be sent to you, reply to all will b also included in to the list, But if he was a man of understanding, he would reply to you,cc to B).
Now say BCC, the reason is BCC people can see you to and cc people, but to and CC people do not see the BCC person's name, for you think it necessary to let a person know, but you do not want to let other recipients know you sent the mail to him, So you bcc it to him. The BCC that we often contact is the kind of thing that a colleague or friend sends out a little bit of irrelevant jokes, which often write the recipient in BCC so that no one knows who you sent it to.
