#iargang -Google introduces “Undo send" function on Gmail.

Google has installed an "undo send" function as a setting on its email service. That means no more moments of utter embarrassment when you realize you've accidentally sent a message to someone you weren't supposed to or sent one with a glaring error in it. The feature has been available in Google Labs, a testing platform, for a while now and was recently introduced in the new Google Inbox app. The feature has now also been rolled out on Gmail for the web. It can be switched on in 'Settings' - with a period of between five and 30 seconds available.
After sending an email, a small box appears at the top of the page which allows the user to "undo" and edit their message before sending again or deleting altogether.
