What is the difference between CC and BCC when Composing an Email
From mail2web.com Wiki
What is the difference between CC and BCC?
Both of these are fields for email addresses to which you want additional copies of your message to be sent.
CC stands for Carbon Copy. A copy of the email is sent to any address that appear in this field. CC addresses are included in the message header of the email and thus visible to all recipients of the message. Hence, it is functionally identical to the 'To:' field.
BCC stands for Blind Carbon Copy. A copy of the email is also sent to any address that appears in this field, but those addresses do not appear in the message header of the sent email. Hence, recipients of the 'To' and 'CC' fields will not know that a copy of the message was sent to the recipients in the BCC field.
