The folks over at Gmail have been busy rolling out all sorts of new features in the last few months but the one they dropped on users today is by far my favorite -- Undo Send.

I don't know a single person who hasn't had the gut-wrenching experience of typing up an email, hitting send, and then realizing you've made a gigantic error. You know the kind: an off-color joke accidentally forwarded to your boss, something written in a fit of anger that should never be read, or an embarassing photo of you at the company picnic wearing a propeller hat. In fact, according to a recent survey, a full 87% of executives say they they've sent or received an email in error.

Google feels our pain. Fire up Gmail, click on Google Labs, and enable this fantastic new feature. If you need to use this panic button, you'd better act quick -- you only have about five seconds to undo send before your email slides into the ether and out of reach. Now if you accidentally send your mother a racy email meant for your spouse you have no one to blame but yourself.
