Best Practices for Tracking Pixels

Best practice 1

A tracking pixel is usually a very small image or resource request that allows a system to record that a message or page was opened or loaded.

In email and advertising contexts, tracking pixels are commonly used to measure engagement or connect user activity to analytics systems.

When the email or page loads, the pixel request is made to a server, and that server can record information about the event.

Depending on the system, that may help a sender or platform understand whether something was opened, when it happened, or what device or client was involved.

Another misconception is that users always notice when tracking pixels are present. In practice, they are often invisible.
