Gmail lets you do much more than simply send and receive messages. It offers a wealth of powerful features and its Labs section is home to a range of experimental add-ons that lets you introduce new features to your favorite mail service. Here is how to undo a sent mail in Gmail using a Labs feature called Undo Send.
Undo Send is an experimental add-on for Gmail that allows you to undo a sent email within 30 seconds after pressing the send button. It is useful in certain situations, for example, if you notice that you made some mistakes or wanted to alter something in the message, you can use the ‘Undo Send’ feature. The ‘undo’ email will be saved in the Drafts folder.
