Sending an email to multiple people used to be a lot more difficult. Manually typing in addresses took time, as did selecting contacts out of an address book. Gmail's "Contact Group" function strips away most of the tedious email selection process. Not everybody wants their email addresses shared with the other people in a group, however. Creating an "Undisclosed" email group lets you clump your privacy-minded friends together while simultaneously giving you a mental reminder to send them messages via blind carbon copy.
Instructions
1. Log in to your Gmail account and click "Contacts" in the navigation column on the left edge of the screen.
2. Click "New Groups" in the navigation column. A window appears asking you to name the new group.
3. Type "Undisclosed" into the field, and then click "OK." If you plan to keep "Undisclosed" groups for several different types of contacts, consider adding a note of description to the name, such as "Undisclosed -- Sales Team" or "Undisclosed -- Parent-Teacher Association."
4. Click on "My Contacts" in the navigation column. A list of your contacts appears in the main pane.
5. Click on the name of a contact whom you would like to add to the "Undisclosed" group. The contact information for the person fills the main pane.
6. Click "Groups" at the top of the contact information, and then click on "Undisclosed" in the list of available groups. Repeat the process for every contact you want to add to the group.
7. Click the "Mail" option in the navigation column when you are ready to send an email to the group. Click the "Compose Mail" option. A new email template appears in the main pane.
8. Click "Add Bcc" underneath the "To" field. A "Bcc" box appears.
9. Click inside the "Bcc" box and begin typing "Undisclosed." The "Undisclosed Group" option eventually appears in the list of auto-completing suggestions underneath the box. Click on it when it appears.
10. Compose the rest of the message and send it out. No one in the group will be able to see the other members' email addresses.
