Google Email - "Undo" Feature!

As reported by MarketingVOX: Mere days after Google unveiled an email preview feature for YouTube videos, Yelp reviews and Flickr and Picasa photos, Gmail Labs is introducing yet another feature that enables marketers to preempt a botched email blast.

Undo Send enables users to effectively unsend emails that were prematurely sent — or that contain errors.

The window of opportunity is a small one, however. "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," writes the Gmail Blog.

"And don't worry – if you close Gmail or your browser crashes in those few seconds, we'll still send your message."

To activate Undo Send, visit Gmail Labs > Settings and switch on "Undo Send." Thereafter, users will see an "Undo" link on every sent email confirmation; once "Undo" is hit, users are sent back to the compose window.
