Many people do not know that most email programs and contact lists on PCs and smart phones what the symbol next to the address is used for.
The purpose of this icon is to give you a map and/or directions.
Simply click on the icon and your device will ask if you wish to
see a map and/or to get directions. Very informative and great
help if you need quick directions. Also, on your smart phone, you
can save the map for offline use, in case you are in an area
without GPS coverage.
