Most SPAM safe and CSS

[Matsaki]

I am making a newsletter HTML mail. I found out that I have to put each CSS markup direkt in the tags, otherwise it's not working in Hotmail, Gmail etc.

Also I wonder wich way is the most safe way to send the HTML mail from a SPAM point of view. HTML Only, Webpage or Text|HTML?

Here is the HTML mail I am playing with: http://sv.ayianapa.nu/nyhetsbrev.html if someone would have a look.

Or is there another and safer way to include the CSS. I get many HTML mail and they all seems to be coded in different ways

If somebody have a much better way I would be happy to pay for some consulting
