How can you protect the privacy of email addresses when you email groups of people?
For security and privacy reasons, it’s often best to use the Blind Carbon Copy (BCC) feature when sending an email message to a large number of people. When you place email addresses in the BCC: field of a message, those addresses are invisible to the recipients of the email. Conversely, any email addresses that you place in the TO: field or the CC: field are visible to everyone who receives the message. Keep in mind that many people do not want their email address to be distributed to people they do not know. For this reason, you should use the BCC: field when sending a message to a large group. Each recipient will receive his or her own copy of the message, but the email addresses of the other recipients will be shielded from view.
In addition, using the BCC: field to conceal email addresses acts as an anti-spam measure. If you use the TO: field or the CC: field to send a message to a large group, it becomes more likely that the recipients will receive unwanted email. This could occur because recipients use the “Reply to All” feature to respond to your message. A second scenario that could create unwanted email involves “spam” programs that are designed to send spam to addresses found in the TO: and CC: fields of messages. The BCC: field protects against these scenarios.
Note: Make certain to type your own or one valid address in the TO: field after you have listed your group recipients in the BCC: field.
