What is the difference between the HTML source view and HTML preview?
The HTML source view shows the markup (source code) used to generate the HTML view. HTML emails are always sent as source code. Mail clients (eg, Outlook) convert source into an HTML view on arrival, or if they do not support HTML email they should look for and display a plain text version of the email. Systems which render source into an HTML view usually vary in the way that they display the HTML view. The Communications Manager preview is a totally accurate display (or at worst a very close approximation) of the way that the MS Outlook, Outlook Express or Internet Explorer (the versions installed on your system) will display the HTML email. Different versions might display it slightly differently, and Eudora, Netscape and other mail systems might also render it differently. The source view is the authoritative view of how the HTML component of the email will be sent.
