Our Beacon is an invisible 1×1 pixel image that you can embed in your email or ad campaigns. When the image loads, it records the event happening in Kissmetrics.
The beacon is a standard tag. The URL points to our tracking servers at trk.kissmetrics.io. Please refer to our API Specifications for how to pass the additional parameters, like who did the event and the name of the event.
Keep in mind that many email clients don’t load images immediately, so your reported numbers will likely be lower than your actual views.
