Almost everyone at some point has sent an email they wish they hadn't! Well, for the first time since the old AOL Mail "Unsend" feature, Google is now making the feature available to Gmail users!
Do you get a lot of work emails? I tend to have to check mine 10,000 times a day. Most of the time, the important messages are buried under spam. By the time I get to them, the time already passed where I needed to give an answer. Work email may be a thing of the past.
