Google Mail Goggles

Ever had a little bit too much to drink, only to send that nasty (or emo) email to your ex-girlfriend at 4 in the morning? Well, prevent such embarrassment from happening with the Google Mail Goggles – a feature that aims to prevent such moments from happening by forcing you to answer math questions before the message is sent. This feature can be set to kick in during certain times, and you can select from various difficulty levels to suit your arithmetic prowess. In order to access Mail Goggles in your Gmail, click the “Labs” tab in your Gmail account’s settings.
