Okay. This is getting interesting.
After trying a variety of HTML options being sent as a file, I used the Power Messenger template option which successfully sent a test of some text.
In going to the template's source:
1. Direct link here to: m2media.com Online Learning</div>
2. Click on the "Movie+PDF" tab to explore the contents</div>
3. When accessing any PDFs, use your password: xxxxx</div>
4. If you need help with any of this, including e-mail subscription help, please contact us. </div>
...I copied that into Dreamweaver's Code View and uploaded it to:
When using that as the fie for Power Messenger, the e-mail still comes in blank.
