The inclusion of a blind carbon copy (Bcc) feature within Outlook email composition provides a method for sending a message to multiple recipients without revealing their email addresses to each other. When utilizing the Bcc field, each recipient receives the email as if they were the sole addressee in the “To:” field. For instance, if a message is sent to recipient A in the “To:” field and recipients B and C in the “Bcc:” field, recipient A will only see their own address in the recipient list, while recipients B and C will see no other addresses.
Employing blind copy functionality offers several advantages. It enhances privacy by preventing the disclosure of recipient email addresses, particularly useful when emailing large groups where recipients may not know each other. This protects against potential spamming or unauthorized contact list harvesting. Furthermore, it aids in maintaining professionalism and etiquette in scenarios where revealing the entire recipient list is unnecessary or undesirable. Historically, the practice of including blind copies mirrored the paper-based practice of carbon copying documents while concealing certain recipient information.
