Unsending Emails Now Possible: Gmail Users Can 'Undo' Embarrassing Sent Emails

Gmail users can now "undo" sent emails. The world's most popular email platform has enabled a feature that lets user set time delay between 5 and 30 seconds before sending an email. You'll have that much time to hit "undo send" and save yourself heartache.

To enable "Undo Send" feature, click on the gear wheel icon on the top right of the Gmail interface and choose settings. You should find an option to set the timer.

Earlier, the option was available as an experimental feature in Gmail Labs but was not quite popular.
