What web browser does CustomMailer use to display the CustomMailer Help file?
CustomMailer opens the CustomMailerHelp.html file in your system’s default web browser, just as if you had double-clicked the CustomMailerHelp.html icon or selected it from the CustomMailer section in the Windows Start menu. You must have a web browser (e.g. Netscape Communicator or Microsoft Internet Explorer) installed on your system to read the CustomMailer Help file. The CustomMailer Help file uses frames, so older or more primitive browsers will not display it correctly.
