Google has finally added an elective “undo send” feature to GMail, which permits you to rapidly block an email from going to the wrong receiver, with lacking details or absent attachments. It’s part of Google Labs, which has lately added YouTube, Flickr and Picasa previews and other email fine-tunes.

The feature permits 5 secs for the GMail user to click “Undo” next to the standard “Your message has been sent” dialogue; this brings back the email to draft-status, and permits not only the receivers but text, attachments and formating to be fine-tuned. What it won’t do is hook back a mail that has already been sent out. To apply GMail Undo, go to Settings and then Labs tab, and the option is down close to the bottom of the list. We would like to experience a user-selectable longer time hold up choice in the time to come.
