New option added in gmail-Undo

Google gonna set an awesome option button in their mail settings called "Undo".Google is making easier to clear our trouble that can be caused by a misdirected or inappropriate email.

An option to cancel the delivery of an email within 30 seconds of hitting the send button is now a standard safeguard in Google's Gmail as part of a settings change made this week.The "undo send" feature had already been available for the past six years in Google's experimental labs, but that required Gmail users taking extra steps to get it.

Gmail account holders will now be able to activate the protection in Gmail's standard settings.
The tool delays the delivery of emails from five to 30 seconds after the send button is pressed to give users a fleeting chance to retrieve an email mistakenly sent to the wrong person.

It could save embarrassment to the billions of people who send emails with mistakes, which they've spotted the moment they've hit the send button.

Google inserted the "undo send" feature last month into its email management application called "Inbox" designed for mobile devices.
