In Microsoft Outlook, there is recall feature to recall emails that you sent unintentionally, or contain mistake that you only notice afterward.

Undo Send, the new Gmail lab feature, trying to handle this incident, on slightly different way. Every time you send an email, an ‘Undo’ link will appear on top of the sent email, for 5 seconds before it is disappear. It is said 5 minutes is enough to notice and catch that email, although I feel this is only suite for short emails.

Clicking the ‘Undo’ link will bring that email back to the compose email screen where you can edit back that email.  Remember, it can’t pull back email that already sent.

The next Gmail lab feature that I wish to have is,  ’recall’ feature, just like what Outlook can do, or even better.
