The popular “Undo Send” feature of GMail has just got better. In case you are wondering what this Undo Send feature is, here is a simple example
Say if you accidentally sent a ‘Love you’ mail to your ex or a Birthday wish which you intended to save as draft, no need to worry. You will now be allowed to Undo the action with “Undo Send”
However, some users were unhappy about the short period of time associated with Undo Send. Google had restricted it for 5 seconds by default. But now, you can change the cancellation period to 5, 10 or even 20 seconds.
Personally, I feel it is a great addition to the ever-improving GMail service. Mind you, it is still a Google Labs feature, so don’t forget to visit the Labs section to change the Undo send period.
