You know the feeling, the immediate dread after hitting send on an email you wish you could take back.
It could be a dickish reply you sent in the heat of the moment and now want to retract, or an email to your office buddy Joe, complaining about what a douche your boss is... that you accidentally sent to your boss instead. Or "sexy" pics you meant to send to your lady that ended up going to the other Jennifer in your contacts- your sister. Yikes.
Well, now Gmail has a feature that let's you "Undo Send".
