Undo Sent mail in GMail

Sometimes I regret sending a message the morning after. Other times I send a message and then immediately notice a mistake. I forget to attach a file or email the birthday girl that I can't make her surprise party. I can rush to close my browser or unplug the Internet — but Gmail almost always wins that race.

Now you can do just that. Turn on Undo Send in Gmail Labs under Settings as shown below


Saving this setting you’ll see a new “Undo” link on every sent mail confirmation. Click “Undo” as shown in the pic below and you’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, it'll still send your message.
