Google Mail won’t let you do that to yourself. Google added a new and very interesting feature to its email service called Undo Send. 

 

However, you have one second to regret the fact that you sent the email and four other seconds to undo the send operation. After those five seconds the email is beyond your reach. 

 

This feature is new only to the Gmail service actually. Microsoft’s Outlook has the Recall button, while AOL e-mail has the Unsend button, but the latter only works if you sent the message to another AOL e-mail user. 

 

Nonetheless, if you are using the Gmail as I do, go to Gmail Labs and there you’ll find an option to turn on “Undo Send.” After you switch that option on, every time you send an email, an “Undo” link will appear on the send mail info. Then you just click the link if you want to change some of the e-mail’s content. 

 

It has its limits though. After the five seconds have expired it’s “hasta la vista baby.” And another thing, if you close Gmail by mistake or not or if the system crashes, Google still sends the message, said Michael Leggett, user experience designer for Google, according to eWeek.com. 

 

It wouldn’t be a big surprise, at least for me, if Google will make those five seconds ten or 15 in the future. Many users already complained about the fact that the unsend time is too short.
