Question

what is the use of BCC​

Answer 1

Answer:

For security and privacy reasons, it is best to use the Blind Carbon Copy (BCC) feature when sending an email message to a large number of people. When you place email addresses in the BCC field of a message, those addresses are invisible to the recipients of the email.

Answer 2

Answer:

It’s kind of funny that a software application would use abbreviations that refer to pre-software days. Remember carbon copies? Cc means carbon copy and Bcc means blind carbon copy. For emailing, you use Cc when you want to copy others publicly, and Bcc when you want to do it privately. Any recipients on the Bcc line of an email are not visible to others on the email.
