Blind carbon copy

Blind Carbon Copy (BCC) is a feature used in email communication. When you add recipients to the BCC field, those recipients receive the email without their addresses being visible to other recipients. This means that people in the "To" and "CC" (Carbon Copy) fields cannot see who was included in the BCC field. The BCC feature is often used for privacy reasons, allowing the sender to distribute an email to multiple recipients while keeping their email addresses confidential.
