It would be a whole lot simpler for you and more universally available (viewable, distributable) for your Visitors if you merely offer your MS Publisher created Newsletter as a managable PDF file instead. 
You can continue to create and produce your Newsletter in Publisher, but if you
download PDF995 (a free sortware that is a converter/editor) it will allow you to save a Publisher file as a PDF --- which is easily configurable as a downloadable file via a simple text link in Blue Voda or any other medium!
* Using a PDF format to distribute documents, Newsletters, or anything else allows you creative control over things, as Users will not be able to overwrite or makes changes to your "Branded" product .... this prevents anyone from copying your logos, written material, etc. and using it in a manner unauthorized by you. Follow the instructions on using PDF995, to "convert" a file to PDF.
1. Instead of SAVE AS you will actually PRINT
2. When your print dialog box appears, you will use the drop-down Menu of "Printers" to select PDF995 as the "Printer" which will then "print" the file to a location you specify (a folder) automatically "saving" it as a .pdf formatted file.
3. You will then FTP this file up to your
public_html/ directory of your VodaHost account so that it can be linked from your web pages for immediate viewable version for your visitors that they can elect to "save a copy" of (download).
An example of a properly formatted hyperlink you will use to link from your page to allow Visitors to download would look like this (substitute as indicated, and be sure to keep the file name short as possible):
http://www.YourDomainName.com/newsletter032008.pdf .... and on we go! .
