A Gmail tool to 'unsend' emails

A life-saver and a job-saver feature inGmail can let users undo the saucy email sent by error to an unintended recipient by a simple click on a button.

Google's Gmail settings can help users from the potential embarrassment but they have to be swift to hit the button.

According to news.com.au, to activate the feature, users can click on the cog icon in the top right corner, and select settings from the drop-down menu, followed by 'Labs' where the 'Undo Send' button can be enabled.

After the option is enabled, each time a mail is sent, the status box that shows 'Your message has been sent', will also say 'Undo' that will appear for roughly 10 seconds.
