TO, CC, and BCC in email explained

What is the the Difference between CC and BCC fields in the email sending

Well the abbreviations of these are: 

• CC stands for Carbon Copy

And

• BCC stands for Blind Carbon Copy

Now

Let me explain their usage through the example.

Suppose you are sending an email to some group of people and you entered emails like below

TO: advertisement@example.com
CC: yourBoss@example.com; YourManager@example.com
BCC: ClientA@example.com; ClientB@example.com; ClientC@example.com

Now when you send this, the below will be in effect.

1. To: These people can see all the email addresses in CC and BCC field including his own email addresses.
2. CC: These people can also see the email addresses in all the fields i.e. in TO, CC, and also in BCC.
3. BCC: These people can see the email addresses in TO and CC field, but they CANNOT see each others email addresses. i.e. ClientA@example.com do not know that the email is also sent to ClientB@example.com and ClientC@example.com, also ClientB do not know about ClientA and ClientC, and likewise ClientC do not know about ClientA and ClientB.
