If the Options setting was ok, then yes, it is how you have the text box
formatted, or your layout. Make sure the font is one of the web friendly
fonts. Do you use any "print" or paragraph formatting. Bullets and columns
create problems. Overlapping elements can create problems...
Usually you have a better chance of not having problems if you do use one of
the Publisher email formatted templates.There is something to your design
that chokes Publisher when the publication is converted to html, and as a
result your text is converted to an image. You basically have to
de-construct your text box until you find the problem. It can be a pain,
until you figure out what you can and cannot do, design wise.
With that said, I would agree with much of what John Inzer said. If you want
the least hassle, and the best looking most foolproof email, then send it as
a PDF attachment. More and more people are going to have problems with html
formatted email, because of the increased security across the board. I think
this is going to be true, regardless of what program you use to generate
your html formatted email. Almost everyone will be able to read your PDF
formatted email.
If you have Pub 2007, you can use the PDF add-on. If you don't you can
download the good little freebit at
www.primopdf.com and use it convert to
PDF.
