In your System Check tool in the ACP you might have noticed a warning "Install the free Geo Location module from the marketplace" and are wondering why you are being requested to install it.

The Geo Location module gets a user's physical location based on their IP Address. This is used by the Mail Core when generating statistics for the Newsletter module (and other modules that can request campaign support).
If you plan on using the Newsletter module installing this module will help you gather more interesting stats about the locations your newsletters are going out to.
