Does anyone know of a free site that has a really good explanation of how to create and send an html newsletter?

All I can seem to find are companies that want to sell me services or sites that argue over the pros and cons of text vs. html. There is no argument. The boss wants html, and he wants it cheap.

I have a very basic knowledge of html, so the clearer the instructions, the better.

What kind of design do you want the newsletters to be? Simple, with graphics, without, with tables etc..? You can code it by yourself and paste the code in Outlook Express' Edit tab in a New Mail or use Frontpage or some other site builder to design your newsletter and again, copy the code and paste it in OE. :)

I got this from here - http://www.techsoup.org/howto/articles/webbuilding/page1601.cfm
Three Options for Creating HTML Newsletters
Now that we've got all of the technical details out of the way, the question now becomes, how do I create these HTML newsletters?

There are three basic options:

Use your current e-mail client.
Use a bulk e-mail client specifically designed for HTML.
Use an application service provider (ASP).

For the first two options, you'll need to dish up images on a Web server, and some basic HTML knowledge will come in handy. For the ASP option, the ASP will host the images for you, making HTML knowledge less important. For information on finding an ASP, TechSoup's Frequently Asked Questions About ASPs can help.
maybe there're some stuff you'd find helpful to read in there, about hosting your images, spam and everything :)

I appreciate the help. Thanks.
