I sometimes receive TrackEngine e-mails without the TrackEngine header. Am I missing something?
This is due to the way some pages are rendered using absolute positional addressing. The TrackEngine header is actually prepended to the HTML being sent, and as a result, may be overwritten by text or images positioned right at the top of the document. To track such pages, change the delivery parameter for that page to [Summarize new content and send me the page].
