How to undo or delete a sent email?
Many a times it happens that in hurry we send an incomplete email and just after hitting the send button we realize that something more to be written or needs to be corrected.
But after sending the email we are helpless. We can't do anything.
But no more if you use Gmail email services, you can undo a sent email but only for 5-7 seconds after hitting the send tab. (The regret still remains as its for limited time but still it can save us many-a-times not always though)
As the feature is in beta stage it is not yet released for normal users but you can enable it yourself.
Here is how to enable this feature.
