Google's products and features attract millions of people to choose Google over its competitors. Gmail offers Labs features and apps on regular basis.
Google launched a potentially cool new feature for Gmail that adds your city, state and country to your Gmail e-mail signature. This experimental Gmail Labs feature that detects your location and appends the city region and country names to your signature.It'll use your public IP address to determine your location, so it may not always be that accurate.If you want more accurate location detection,You can also opt to install Gears, which supports a location module that’ll use Wi-Fi signals to better pinpoint your present place to recognize that you're actually where..
Gmail Software Engineer,Marco Bonechi said this is the perfect solution for persons who are frequent travelers.
To enable this feature,go to Labs tab under Settings,turn on Location in Signature,then go to your signature preferences and check the box next to "Append your location to the signature".
You'll always be able to disable the option or just delete your location from specific emails whenever you want.
