In mail cc and bcc means

In email, CC and BCC are two common abbreviations that stand for:

CC - Carbon Copy

When you add someone's email address to the CC field, it means you are sending a copy of the email to them, but they are not the primary recipient. The CC field is used to keep others informed about the email, often for informational purposes or to keep them in the loop.

BCC - Blind Carbon Copy

When you add someone's email address to the BCC field, it means you are sending a copy of the email to them, but their email address will not be visible to the other recipients. The BCC field is used to send emails to multiple people without revealing their email addresses to each other.

In other words, CC is like sending a copy of the email to someone, while BCC is like sending a private copy of the email to someone without anyone else knowing they received it.
