If you haven't heard of it yet, Gmail has recently introduced the "Undo Send" feature to recall an e-mail that you've sent.

This latest tweak allows you to reclaim your sent mail if it happens to be within 5 seconds of hitting the "Send" button. And that’s nothing short of an official manna from heaven as far as habitual offenders like me are concerned - my entries to the e-mail hall of shame are one too many as I most often end up clicking the "Send" button on my e-mail instead of the "Save" button.

Go on to your email settings and enable the feature if you need a helping hand to undo your e-mail gaffes.
