Tracking custom data with tracking pixels and links

By default, your tracking pixel will be tracking IP-addresses, user-agents and the date / time of opening. But as a premium user, you can also track custom data that you embed with your tracking pixel. By altering your tracking pixel url, you can add your own data.

Tracking pixel with custom data

For example, if you want to use the same tracking pixel over 3 separate mails, but still want to know which mail triggered the tracking pixels, you can add custom data. If the url of the tracking pixel is "", you can create three separate urls, which each different custom data:

  • ""
  • ""
  • ""

Then, you send each of the tracking pixels separately in your different mails. When you open up your email tracking page, and scroll down over to the ‘Custom data’ panel, you can pick which view you want to use: Donut or table (you can always switch between them):

If you pick the donut view, you will see your custom data visualized in a donut graph. If you track a lot of different custom data, the donut graph may become cluttered, and you might want to use the table view.

If you pick the table view you will see your custom data in a table. You can sort this table by the data name or by the times opened.

Custom data table

This was only one example on why to use custom data, but there are countless other applications. One of which, is to track which email address or user has opened your email.

You can also add custom data to tracking links. At the moment, those don’t get visualized. But you’ll be able to see it when you view the raw data.

All custom data get exported when you create a CSV-export of your tracking pixel or tracking link.
