Google announced today a new and interesting experimental feature in Gmail Labs that allows you to undo and edit emails as soon as they are sent, offering the possibility to correct some information or even decide to cancel it.
Unlike what you might be imagining right now, the magic of Gmail does not pull messages back from the destination server to «undo» the action. The functionality, however, delays sending for 5 seconds, offering a way to cancel the sending or supplement the information.
According also informed the internet company, even if your browser or Gmail crashes after sending, the message will be sent normally without any error.
