Options for adding message recipients

Add recipients (cc)

When you add recipients to your message, you have the option to add a "cc" field. Anyone in this field will see the other recipients of the message.

"Cc" is often used to add recipients to an email who don't need to take any action.

Hide recipients (bcc)

If you're sending a message and want to hide a recipient's email address, you can add them in the "bcc" field.

How "bcc" works

  • The recipients won't know that you added anyone to bcc.
  • Anyone you add to the "bcc" field will see that they were added using "bcc." They will also see message recipients in the "to" and "cc" fields. Note: If they don't use Gmail, they may not see this information.
  • People you add in "bcc" can't see the name or email address of anyone else you add in the "bcc" field.
  • If people reply all to a message, people in "bcc" won't see the reply.
Send an email to multiple recipients

When you write a message, you'll add the recipients in the "to," "cc," or "bcc" fields.

To add multiple recipients, put a comma between the names or email addresses of the recipients.

If you need to send an email to a large number of people, you can also create a group, then add that group's email address in the "to" field.
