Email template html

How can create an email template or change the default email template html wise? not just content
Thanks

If you go to the config tab in the admin console you can edit email templates. If you already knew that, please clarify your question. Not sure what you mean by HTML vs content.

The email template body is HTML. You can put whatever you want in there.

Could i use MS Word templates? I have few good templates, i took ready-made solution from the http://www.nl.poweredtemplate.com/brochure-templates/newsletters/free/index.html and edit it for my needs. So is it possible to use my old templates or i should order new one in HTML format?

MS Word templates use a combination of MS specific XML and HTML. You should build your email templates in HTML proper.
