Gmail Panic Button

Have you ever had an experience where you sent an important email and just realized that you mispelled something? Or forgetting to attach file? Gmail is now working on a new feature that could undo your the sent message as long as it’s still within 5 seconds of the time you’re sending it. You could activate this option by activating the Undo Send option in the Settings.

Turn on Undo Send in Gmail Labs under Settings, and you’ll see a new “Undo” link on every sent mail confirmation. Click “Undo,” and we’ll grab the message before it’s sent and take you right back to compose.

This feature can’t pull back an email that’s already gone; it just holds your message for five seconds so you have a chance to hit the panic button. And don’t worry – if you close Gmail or your browser crashes in those few seconds, we’ll still send your message.
