Did you know that you can Undo your e-mail sent in your Gmail?
Yes, you can! And recently, it got better by adding 30 seconds delay on its feature. 🙂 Cool!
Here’s how you are going to do it.
First, you have to (have Gmail account.. Hehe!) activate the feature via their Labs – click Settings menu on the upper right corner of your screen.

Second, turn it on to activate the feature.

Third, select your time delay. In the early stage of development of this feature, only 5 seconds was the only choice, which did not gain popularity because its quite tight to change your mind in 5 seconds. Later, 10 and 20 seconds were added, and very recently the 30 seconds options was made available.

Now is the WARNING. This feature is pretty much cool if you are not sending e-mail immediately. Because once you turn it on, it will delay the sending of you e-mail depending on the delay you set. On the other hand, its pretty cool to have a least half a minute to pause and check whether you are cancelling the e-mail or not.
Try for yourself. 🙂
