Have you ever regret sending a message that you shouldn’t have? or may be a mail that is incomplete. Any formal email can’t be send twice just to cover up the content for the previous one. Google recently introduced a feature called “Mail Goggles”
Mail Goggles will check that you’re really sure you want to send that email and what better way to check than by making you solve a few simple math problems. Once you have verified the answers you’re probably in the right state of mind.
Note that Mail Goggles active late night only on the weekend. This is the time you’re most likely to need it. Once enabled, you can adjust when it’s active in the General settings.
Mail Goggles will prevent many of you out there from sending messages you wish you hadn’t.
