Google is further streamlining its services by offering an option to include Google Maps previews whenever you receive an address via Gmail or Google Buzz.
The good folks at the Gmail Blog posted a quick and easy how-to:
Enable "Google Maps previews in mail" from the Gmail Labs tab under Settings, and any time you receive an address or a Google Maps link in an email, a preview will appear containing an interactive Google Map of that location. Any Google Maps URL will work, but we currently only extract US addresses (we're working on making addresses around the world work).
Try it for yourself here, or check out an example below.
