BCC

BCC, or Blind Carbon Copy, is a feature in email communication that allows you to send a copy of an email to someone without revealing their email address to the other recipients. When you add someone as BCC, they receive the email, but the other recipients won't see that person’s email address. This is useful for discreetly informing someone or maintaining privacy, such as when you want to keep a recipient's involvement confidential. BCC helps prevent reply-all issues and keeps recipient lists private when necessary.
