GMail Introduces Undo Send

Undo Send has just been added to Gmail. It doesn't mean that you can reclaim an email that has been already sent. Instead, it is waiting for 5 seconds during which you can cancel the action of sending the email. After those 5 seconds, you mail will be sent, even if you close the window or if you computer reboots.

Undo Send is a much smarter feature. We've all regretted pressing "send" on e-mails. Sometimes we realize, too late, that our message is a "reply all" when it shouldn't be. Or that we spelled something wrong. Or that we were angry and shouldn't have sent it at all. Undo Send lets you snatch an e-mail back before it gets sent out. But you have to act fast.

Google product manager Keith Coleman told me that internal testing of the feature, which was created by a Google engineer in Japan as a side project, indicated that five seconds was an appropriate compromise between the ability to recall an errant message and the need to not introduce lag to e-mail conversations. "Adding a delay could be potentially frustrating," Coleman said. I'm not sure the rest of the world is as agile with the mouse as Google's internal testers, but Coleman also told me there's an option to increase the un-send time window to 10 seconds. "We may decide to add longer options," he said.

To enable the feature, go to Gmail Labs and click the "Undo" link.

That's a really nice feature. We send things sometimes we don't want too. I hope yahoo introduces it too.

Very Nice Feature. Thanks for the info
