It attempts to deconstruct tracking links and pixels and highlight the data that is being collected. ConvertKit's tracking links are of the form https://click. The destination URL is base64 encoded and embedded in the tracking link as part c. What about a and b? There's probably an email or subscriber id in there. Searching for the text k0u30rg2pds6hqzw2vtl in the email shows that it's in every tracking link. If the server side database of tracking links is down, ConvertKit can fallback to using c as the destination URL. Substack Tracking links. Substack has the most unfriendly and user-hostile tracking links that I've seen. My email newsletters don't have tracking links as I disable email tracking with Buttondown.
