Ever sent an e-mail to a friend, colleague or boss on a rash moment of impulse, only to regret it later?
That could soon be a thing of the past as Google - after years of testing - finally makes available its new "undo send" feature on Gmail.
The feature can be turned on in the settings pane directly below a user's profile picture on the top right hand corner.
The user will then need to check the "enable undo send" function and can choose a five, 10, 20 or 30 seconds cancellation period from a drop-down list.
'Undo send' is available on all web accounts, while mobile users will need to download Google's Inbox by Gmail app in order to gain access to the feature.
