About the accuracy of geographic location data

Direct Mail displays the geographic location of a subscriber or user in a few different places, including:

  • Campaign report email open tracking
  • New subscriber email alerts
  • Direct Mail account control panel (under the Activity section)

This location data is an approximation based on the IP address of the user. It is not obtained via GPS or any other location-tracking mechanism.

The user's IP address is compared against a professionally-maintained database that attempts to match IP address to geographic location. However, due to the nature of how the internet works, there are limits to the accuracy of location data obtained in this manner. Accuracy may be limited by the following factors:

  • Some Internet Service Providers (ISP) do not provide accurate location for the IP addresses they own
  • Users accessing the internet via VPN or proxy are hidden behind the proxy's IP address, which may be located far from the actual user
  • Some mobile web browsers (like Opera Mini) proxy all traffic through a different server which may be located far from the actual user
  • Location information for IPv6 addresses is not available

It is best to treat geographic location data as an approximation or estimate.
