Tracking pixels guides

A tracking pixel connects an image-loading mechanism to an event record. Understanding that connection is the starting point for deciding what a report means and whether the information is useful for your purpose. Articles under this tag examine the mechanism, the surrounding workflow, and the gap between a recorded request and the conclusion a sender might want to draw. They also consider how the measurement should be described to the people involved.

Read the tracking pixel overview first if you need the basic vocabulary. Choose the email-open material next when evaluating a report, and the privacy material when reviewing collection choices. Developers should follow the event through its full path and note where information can be missing, repeated, or transformed. Nontechnical readers can focus on the questions a vendor or implementation owner should answer. In both cases, define the intended use of the signal before treating a dashboard number as evidence of a particular person's behavior.
