i tryed to monitor newletter reception via piwik goal tracking. The goal is configured like “Goal is triggered” “when visitors” “Visit a given URL (page or group of pages)” that “is exactly” a url like “http://www.domain.tdl/index.php?goal=newsletter”. Direct url calls result in a goal conversion. But including a iframe into a html-email-content with the iframe source “http://www.domain.tdl/index.php?goal=newsletter” dont. Does anybody has an idea how to make this work or what other posibilitys piwik provides to track newsletter receptions.
