Gmail will allow you to recover messages sent by mistake

The feature is called “Undo Send” and is already available, making use of this user can cancel the sending of an email message sent from Gmail, this function only has a peculiarity that is none other than allowing this recovery when it has elapsed a short period of time from when it was sent until an attempt is made to retrieve (you have five seconds to retrieve it).

Thus, every time a message is sent with the “Undo Send” function activated, a button called “Undo” will appear, allowing the sending of the new e-mail message to be recovered. Thus, a new message composition window will appear and confirm the non-sending of said email.

At the same time, Google Labs have included new features in this email client, such as viewing the content of your email on services such as YouTube, Flickr or Picasa.
