A Blind Copy or bcc (blind carbon copy) is an essential feature in email communication that allows the sender to send a copy of an email to one or multiple recipients without those recipients being visible to the primary and other secondary recipients. This feature is symbolized by “bcc:” in email interfaces.
Importance of Blind Copy
Using the bcc: field is critical for:
- Privacy: Keeping the email addresses of recipients confidential from each other.
- Security: Preventing unauthorized access and exposure of personal email addresses.
- Spam Reduction: Reducing the likelihood of email addresses being harvested for spam.
Best Practices
- Mailing Lists: Always use bcc when sending emails to a large multiple-recipient list to maintain privacy.
- Sensitive Communications: Use bcc to protect the identity of recipients in sensitive communications.
Technical Context
How it Works
When an email is sent using the bcc: field, the email is delivered to the bcc recipients without showing their email addresses in the header of the email received by other recipients.
Example:
1To: john@example.com
2Cc: jane@example.com
3Bcc: confidential@example.com, private@example.net
- To field recipients: visible to all.
- Cc field recipients: visible to all.
- Bcc field recipients: invisible to other recipients.
Email Header Structure
In the email’s source code, the bcc: field is handled by the email client and server, ensuring the addresses are stripped out before delivery to other recipients.
Historical Context
The concept of bcc dates back to the early days of electronic mail, evolving from traditional carbon copies (cc) in typewriting. The introduction of bcc as an electronic feature in modern email clients has significantly enhanced user privacy and communication efficiency.

Summary
