In Outlook for Windows, select Options > BCC. On the web and on Mac, click "BCC" next to the "To" field. On Android, iPhone, and iPad, tap the arrow to the right of the "To" field. Finally, add the recipient's email address to the BCC field.

You can use the blind carbon copy (BCC) field to send a copy of an email to others without showing their email addresses to the primary recipients. Here’s how to add a BCC in Outlook on Windows, the web, Mac, Android, iPhone, and iPad.

What Is Blind Carbon Copy (BCC)?

Blind carbon copy (BCC) allows you to send a copy of an email to the recipient(s) you enter in the BCC field. However, the other recipients won’t see the email addresses of those entered in this field.

The BCC option has many uses. For example, you might decide to BCC your supervisor so they can see a message without alerting your coworker, who is the key recipient. Or, you might email a complaint to a company and BCC your spouse, so they have a record of the message without displaying their email address to the company.
