Gmail adds ‘undo send' button

If you've ever sent an email, then immediately wished you hadn't, you'll like Gmail's newest option.

Gmail is adding a “undo send” button that gives users the option to set a time delay of between 5 and 30 seconds before an email is sent.

You can enable the function by clicking on the gear wheel icon at the top right of the Gmail display hub, then click "settings."

Google has already started updating accounts, but it could take two weeks for everyone to see the changes.
