Blind cc mac mail

You're looking for a way to use the "Blind Carbon Copy" (BCC) feature in macOS Mail!

To add a BCC recipient in macOS Mail, follow these steps:

1. Compose a new email or reply to an existing one.
2. Click on the "To" field and start typing the email address of the recipient you want to add to the BCC list.
3. As you type, a dropdown menu will appear with suggestions. Select the email address you want to add.
4. Once you've selected the email address, a small icon will appear next to it, indicating that it's a BCC recipient.
5. To add more BCC recipients, simply repeat steps 2-4.
6. When you're finished adding BCC recipients, click the "Send" button to send the email.

Note: When you add a BCC recipient, their email address will not be visible to the other recipients on the "To" and "CC" fields.

Alternatively, you can also use the keyboard shortcut "Command + Shift + B" to quickly add a BCC recipient.

I hope that helps!
