How to Send an Email to Undisclosed Recipients from Gmail

This trick lets you hide recipients' addresses.

When you put multiple addresses in the To line of an email, every recipient sees notonly your email's content but also all the other email addresses to which you've sent your message. This can be problematic because most people prefer not to have their email addresses shared widely. If you merely move the addresses to the Ccfield, the effect is the same; they just appear on a different line.

Use the Bcc field, though, and you become an instant privacy hero.

Any address entered in this field is hidden from all recipients. One problem: You have to enter something in the To field. This workaround solves the problem.

Using the Bcc Field

Here's how to address a message in Gmail so that it goes to "undisclosed recipients" (with all email addresses hidden):

  1. Click Compose to start a new message. You can also press c, of course, if you have Gmail keyboard shortcuts enabled.
  2. In the To field, type Undisclosed recipients < followed by your Gmail address and a closing >. For example, if your Gmail address is, you'd type Undisclosed recipients <>.
  3. Click Bcc.
  4. Type the email addresses of all intended recipients in the Bcc field, separated by commas. (In Gmail, hitting Enter after each address works as well.)
  5. Type the message and its subject.
  6. Click Send.


  • If you're uncomfortable not letting recipients know that others are receiving the same message, just add a note to the beginning of the message that lists the recipients (minus their email addresses).
