Jim,

        What if someone has their client to send E-Mails as only text format, and
not HTML?  Does readnotify.com change the format of an E-Mail?

        Would closing the preview pane, and then selecting the MSG, and saving it
as a text document defeat their tracking?  I mean if you've closed the
preview pane, and then save the E-Mail as a text document you haven't
opened the E-Mail itself, right?

Herman
Live Long and Prosper
