There’s a part of Gmail that I rely on almost daily that, until today, had actually not been an official feature built into the software. Instead, you needed to turn it on using Google Labs. The feature — my favorite from the service — is called Undo Send, and it’s as simple as it sounds.
All Gmail users can visit the General settings tab to activate the feature and then choose a specific cancellation period. Once activated, each time you fire an email you’ll have a buffer of time to pull the email back by tapping “Undo send.” It’s perfect for when you realize a last minute typo, or decide to change your mind on something after reacting rashly.
For those of you who, like me, already have this feature active, Google promises that it will remain active by default. The company’s “release track” says it should hit all users within the next two weeks.
