Why Your Email Tracker Shows the Wrong Location (and What to Trust)

You know your recipient sits in London. Your tracker reports the open came from Council Bluffs, Iowa. Nothing is broken — you are looking at a Google datacenter, and this is the single most misunderstood field in email tracking.

Why it happens

Location in email tracking is derived from the IP address that requested the tracking pixel. That works only if the request came from the reader’s own device. For Gmail, it never does.

Gmail proxies every remote image through Google’s infrastructure. Your pixel is fetched by a Google server, and the IP address that reaches your tracker belongs to whichever datacenter handled it — frequently in a different country from either of you. Apple Mail does the same through its own relay. Yahoo proxies too.

The other causes

• VPNs. Increasingly common, and they place the reader wherever the exit node is.
• Corporate networks. A large company often routes all traffic through a few central gateways, so every employee appears to be at headquarters.
• Mobile carriers. Cellular IP geolocation is frequently accurate only to the country, and can place a subscriber in a city hundreds of miles away where the carrier’s gateway sits.
• Security scanners. A corporate mail gateway fetching your pixel before delivery reports the appliance’s location, typically a datacenter.
• Plain database error. IP-to-location databases are estimates, and they are wrong at the city level far more often than their confident presentation suggests.

Which signals actually carry geography

The distinction that matters is proxied versus directly loaded:

1. 1A click is the most reliable signal. Clicking opens a real browser on the reader’s own device, so the request carries their actual network — subject to VPNs and corporate gateways, but genuinely theirs.
2. 2A directly-loaded open — from a client that fetches images itself rather than through a proxy — carries real geography too. Some desktop clients and Apple Mail with Privacy Protection disabled behave this way.
3. 3A proxied open carries nothing. Gmail, Apple Mail with MPP, Yahoo. The location is the proxy.

A tracker that understands this will show "not determined" for a Gmail-only thread rather than inventing a city. That looks like a missing feature and is actually the honest answer — a made-up location is worse than no location.

The mistake this causes

Sales teams misread this constantly. "The prospect opened from Singapore — they must be travelling, I will adjust my call time." No: the message was routed through a Singapore datacenter. Scheduling a 3am call on that basis is a self-inflicted wound.

A related trap is concluding a contact has left the company because their opens now report a different city. Datacenter assignment shifts for reasons that have nothing to do with the person.

What to use instead

For timezone, use what you know rather than what you infer: the company’s stated location, their LinkedIn, the timezone in their calendar link, or simply the pattern of when they reply. Reply timestamps are excellent timezone evidence and are not proxied by anything.

For engagement, ignore location entirely and use the signals that survive proxying — repeat opens over days, clicks, and replies. That ordering is the argument in an open is not intent and in open rate vs reply rate.

One legitimate use

Location is genuinely useful as a consistency check. If a thread has shown Frankfurt for weeks and suddenly shows Sydney, something changed — a VPN, travel, or the message being forwarded to somebody new. The absolute value is unreliable; a change in it is a signal worth noticing.

MailSenseAI deliberately reports location only from signals that carry real geography — clicks and directly-loaded opens — and shows "not seen yet" rather than a datacenter for Gmail-only threads. It is a smaller claim, and it is the true one. More on the mechanism in how email open tracking works.
