How do you unsend an email? Probably you can’t. Outlook had a thing that tried to do that but I don’t think it ever worked. Pretty much once an email goes, you’re done.
But if you are using Google Gmail with a web interface you have ten seconds to unsend an email. So if you are reading this blog post to unsend an email you have just sent, you better READ FAST.
You have to set it up first. Here’s how.
This works on desktop browsers, probably not on any mobile devices unless you have a pad that has convinced Google it is a desktop or laptop.
Personally I’d like to see an option to give the undo send thing a longer period of time, that could be overridden on a message by message basis. I personally almost never have the desire to unsend a message, but when I do, I need more than ten seconds to realize it.
