Gmail's offers cool new 'Undo Send' feature

Have you ever sent an email and then immediately regretted it afterwards?

Google has come up with something for just that type of thing. There is now a new feature available for all Gmail users called Undo Send.

The feature will catch any messages before they are delivered to the recipient within moments of sending it. 

Undo Send can be activated from the Settings/Labs tab in Gmail.

Once the feature is enabled, an Undo option appears after you've sent a message. You have five seconds to click it. Hit it in enough time and the email will be stopped in its tracks.
