How to Send an Email to Undisclosed Recipients From Gmail

Protect email recipients' privacy when sending Gmail messages

What to Know

  • Add all the addresses to the Bcc field. Optionally, add your email address to the To field.
  • Each recipient receives the email, but they can't see the names of the other recipients, which protects everyone's privacy.

This article explains how to send a message to undisclosed recipients in Gmail using the Bcc field.

How to Send Email to Undisclosed Gmail Recipients

To send a message in Gmail with all email addresses hidden:

  1. Select Compose in Gmail to start a new message.

    You can also press the C key to bring up the message composition window if you have Gmail keyboard shortcuts enabled.

  2. In the To field, type Undisclosed recipients followed by your own email address within angle brackets. For example:

    Undisclosed recipients

    To undisclosed recipients in Gmail
  3. Select Bcc.

    If you don't see the Bcc field, click Bcc on the top right of the message you created. You can also use the Gmail keyboard shortcut Ctrl+Shift+B (Windows) or Command+Shift+B (Mac) to display the Bcc field.

How to Make an Email Group in Gmail

If you frequently send messages to the same group of recipients, consider creating an email group in Gmail:

  1. Open Google Contacts and check the box beside each contact you want to include in the group.

    Selecting contacts in gmail
  2. Select the label above the list, then select Create Label in the sidebar.

  3. Enter a name for the new group and select Save.

    Create new label for Gmail contact
  4. To add more contacts to a group, select the contact(s), then select the Label icon and choose the group.

    Manage Gmail contacts labels
  5. A check mark will appear next to the group name. Select Apply to add the contact(s) to the group.

    Applying a label in Gmail contacts

When composing an email, type the name of the new group in the Bcc field. Gmail will populate the field with the complete name, and no one in the group will be able to see the addresses of any other recipients.

If you want all recipients to know who else is receiving the message, add a note at the beginning that lists all recipients minus their email addresses.

No Mass Mailings

You can't use these methods for large mailings. According to Google, free Gmail is meant for personal use, not for bulk mailing. If you attempt to add a large group of recipients in the Bcc field, the entire mailing may fail.

What About Reply All?

Email addresses in the Bcc field are copies of the email only. If a recipient chooses to reply, they can reply only to addresses listed in the To and Cc fields. For this reason, Bcc is a great way to stop a reply-all chain before it starts.

  • How do I unsend an email in Gmail?

  • How do I block an email address in Gmail?

    To block a sender in Gmail, open a message from the sender and select More (three dots) next to Reply. Select Block Sender > Block. The sender won't know that they've been blocked. 

  • How do I schedule an email in Gmail?

    To schedule an email in Gmail, compose your message and select the arrow next to Send > select Schedule Send. In the pop-up window, choose from the sending time options or select Pick Date & Time to choose an exact date and time > select Schedule Send.
