Unsend Sent Messages

Unsend Sent Messages_

This is one of the most useful Gmail tricks. Go to  Settings > General tab and check off “Enable Undo Send.” You can also set the cancellation period as 5, 10, 20 or 30 seconds. Click on Save Changes at the bottom of the page. Next time when you send a message, you will see an Undo option in yellow below the search bar. You can click on it to unsend the message, and then you can edit it or discard it.
