You want to call back a sent email message ? Google's Gmail now gives users a brief period to hold back the sent messages.
A new feature - "Undo Send" introduced in Google's Gmail program that holds a message for five seconds before it is being sent. Gmail's sent mail confirmation message now includes an "Undo" link. Clicking on "Undo" will return a message to its original draft form.
The feature does not allow a user to recall a message that's already been sent.
Really useful feature. So, you have five seconds to decide - to send or not to send !
