Send or unsend Gmail messages
You can send or unsend messages from a browser or the Gmail app.

- In the top left, click Compose.
- In the "To" field, add recipients. If you want, you can also add recipients in the "cc" and "bcc" fields.

Options for adding message recipients
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.
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.
- The people you added in the "bcc" field will see the list of message recipients and see that they were added using "bcc." 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.
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.
