If you opt into the “undo send” feature in Google Labs, you can get a second chance in Google’s Gmail. Writes Philipp Lenssen:
When you now press Send on an email (say, something with the headline “I am quitting my job!” or so), you’ll be returned to your inbox, but above the messages you’ll see “Your message has been sent. Undo View Message”.
Google Subnet’s Joanne Cummings notes that, unlike Mail Goggles, this feature is “actually useful.”
