Undo send is a feature of Gmail that lets you cancel sending an e-mail for a short time after you click the “send” button. The undo send prompt appears for a brief time immediately after you send an e-mail in Gmail. When the e-mail is sent, a menu pops up, showing Message Sent, Undo, and View Message.

If you click Undo, it cancels the sending of the e-mail, and takes you back to the message draft, allowing you to make changes or delete the message.
