After a long, long time in Beta testing, Google has finally made Unsend a feature that everyone can use, here’s how to turn it on:
So how do you enable Gmail’s undo feature? Go to the little cog icon in the upper righthand corner and select “Settings.” About a third of the way down the page you’ll see the “Undo Send” section. You can choose between 5, 10, 20 and 30 second windows of unsendability. Make sure you hit “Save Changes” at the bottom and you’re all set.
A feature like this would seem to be useful for social media as well.
