Best Email Feature Ever!

Ever send a NSFW email to your boss?? Whoops! This will take care that.

It's the "undo-send" button; and it's exactly what you think. You can click the undo-send button and it's being offered to Gmail users.

To enable the feature just click on Settings > General.

So the next time you accidentally send that invite to someone who wasn't invited...don't you worry, just undo-send!
