Can email tracking tell you where someone opened your email?
Short answer: it can tell you roughly where a network request came from, and that is frequently not where the person is. Some tools present that guess as a city on a map. The honest description is that you are looking at the location of a network, sometimes a data centre, and only sometimes a human being. Here is what actually arrives, and the four reasons the city on the map is unreliable. Does…
Email tracking can provide a rough idea of where an email was opened, but it's not precise and often doesn't reflect the recipient's actual location. When an image referenced in an email is fetched, the server receiving the request will have an IP address and a user agent string. The IP address can be mapped to a location, but this is only an approximation, as it may not correspond to the recipient's real location. Here's a breakdown of the four main reasons why the location data from email tracking is unreliable:
1. Provider-side image proxies: Some email providers fetch images on their own servers and serve a cached copy to the recipient. In this case, the request comes from the provider's infrastructure, which is usually a data center. The city displayed for the location is the one associated with that data center, not the recipient's actual location.
2. Mobile networks: When an email is opened on a mobile device, the traffic often goes through the carrier's network, which aggregates traffic through a limited number of egress points. This means that a person's location appears to be in a different place than where they are actually reading the email.
3. Corporate networks: If the recipient is using a company with a centralized egress point, every request they make will appear to come from that location. This means that two colleagues in different countries might show the same location, and a home worker using a company tunnel might appear to be at their office.
4. Privacy relays and VPNs: These tools are designed to obscure the recipient's IP address. When using a relay or VPN, the location you receive is that of the relay, not the recipient's actual location. There's no way to determine if this is the case without explicit confirmation.
Given these limitations, the only reliable information you can get from email tracking is the country of the recipient, sometimes with less certainty. While it might be tempting to infer more from this data, such as whether a client is reading an email from their office or home, the mechanism cannot support such inferences. It's essential to remember that location data is a transport artefact, not a reflection of the recipient's whereabouts.
If you're hoping to learn more about the recipient, you'll need to rely on other methods, as email tracking alone cannot provide that information.
