I am having some trouble with tracking reads. I have the [wpmltrack] shortcode inserted in my footer but I am seeing 0 reads. I am just in testing mode now so I am only sending to a handful of my own email addresses (gmail, yahoo, hotmail), which may cause problems I suspect if they are blocking any tracking image. What I would like to know is what code exactly should I look for in my original source for the email to verify that the shortcode is being implemented correctly? Where I think it should be in my footer I don't see any kind of wpml-specific HTML so I suspect maybe it isn't getting added correctly.
