The forms built into Google Docs are handy devices. We’ve talked before about how easy it is to create a form and have the resultant data stored in a Google Docs spreadsheet for later use but many people are looking for more immediate gratification.
It is a little buried, but Google does make it fairy easy to do this Anyone who has access to view the spreadsheet behind the form can go the Tools menu and select Notification Rules.

The next step is to click that you want to be notified when “A user submits a form” and Notify me with “Email – right away”.

Once you’ve saved this, you’ll be receiving your emails right away!
