One of my ST members just purchased from a site called msgtag dot com. I had never heard of it. I had a look and the idea is that you are alerted whenever your email is opened. A very handy thing to have, especially when email marketing. I know this can be done by imbedding an image that is read from my server so I can track when the image is loaded, but it failes when mail clients block external image requests. Does anyone know if msgtag works differently?
