You guys, this is major. Gmail has unveiled its new "Undo Send" feature, a brilliant feature we've all been longing for since -- well, since email was first invented. It's exactly what it sounds like. If you accidentally/on purpose send an email and then regret sending that email, you may now pull it back from the cruel clutches of the recipient's inbox and pretend that never happened. How might you work this little miracle?
Mosey on over to the Google Labs section, scroll down to the bottom until you see Undo Send, and click "Enable." Enable! Was ever a happier word ever coined? Hit "Save Changes" before leaving that page. Now when you send an email, along with that "your email has been sent" yellow bar you'll also get an "undo send" option. But you'll only have 10 seconds to click it, so hurry! Also, we don't know how long Google will let us keep undo send, so enjoy it while it lasts.
