If you make a typo or regret sending a message, you can undo the action by enabling "Undo send." This setting gives you the option to take back a message you just sent.
To enable Undo Send:
- Click the gear in the top right .
- Select Settings.
- Scroll down to "Undo Send" and click Enable.
- Set the cancellation period (the amount of time you have to decide if you want to unsend an email).
- Click Save Changes at the bottom of the page.
- If you had Undo Send turned on in Gmail Labs, your Undo Send setting will be on by default.
- To test the feature, click the Compose button at the upper left corner of your Gmail account page.
- Compose a message and then click the Send button.
- At the top of the screen, you'll see a message that says: "Your message has been sent. Undo. View Message."
- To prevent the message from being sent, click the Undo link.
- Gmail stops the message from going out and displays it in case you wish to make any changes and then resend it. If not, you can simply close the message, and it's relegated to your Drafts folder where you can keep it or delete it.
Note: To give you time to undo, Gmail delays sending the message for a few seconds. So if you don't select "Undo" within the time limit, your message will be sent. "Undo send" may not work if you experience connection issues.
