All those who tend to get themselves into unpleasant email 'situations' every now and then can finally relax, thanks to an 'undo send' feature launched by Gmail.

Any user can enable the new feature in 'Gmail Labs' under 'Settings'.

If a user feels that the email he just sent should be stopped, he or she should hit the 'undo send' button.

However, the user intending to stop the mail from being sent would get only five seconds to hit the button, reports the New York Daily News.
