Gmail: Undo Send Email

I am sure most of you are aware of this new gmail facility:

Undo Send email.

"Sometimes I regret sending a message the morning after. Other times I send a message and then immediately notice a mistake. I forget to attach a file or email the birthday girl that I can't make her surprise party. I can rush to close my browser or unplug the Internet — but Gmail almost always wins that race.

An email to the wrong Larry pushed me over the edge. I could undo just about any other action in Gmail — why couldn’t I undo send? Many people agreed, including Yuzo Fujishima, an engineer in the Tokyo office. My theory (which others shared) was that even just five seconds would be enough time to catch most of those regrettable emails.

And now you can do just that. Turn on Undo Send in Gmail Labs under Settings, and you’ll see a new “Undo” link on every sent mail confirmation. Click “Undo,” and we’ll grab the message before it’s sent and take you right back to compose."


This will let you cancel the sent email even if you clicked Send button.
But it works only if you click undo before 10 seconds.

It just delays your email for the time that you can actually set after you add this labs in your gmail. You can get the setting in the general tab , undo send seconds. Maximum is 10 seconds.

But i really wish we can undo at any time if the reader has not really read my email. Lets take 1 day also. If he didnt read my email , then i can still delete that email from his inbox. I hope this dream will also come true soon.

Lets wait for the best labs to come. :)
