There are two different forms of HTML ezines. HTML = HyperText Mark-up Language - basically it's language of World Wide Web. It's there, even if you don't know it's there. The end result of this "code" is a web page you view through your email program.
There are three types of ezines (at this time). Text ezines, those of you who remember typewriters, look like they've been typed. A simple HTML ezine contains color, bold, italics, and bullets and is created right in your email program. More complex HTML ezines contain graphics and are created as web pages. When you receive an ezine that contains color or pictures, that's an "HTML" based ezine.
It's very easy to make an HTML ezine if you know how to code HTML or have a web design program, or have a web design program (or webmaster). If you're designing an HTML ezine for your business, then branding is important. So use your webpage as your template. This way your newsletter and your website look consistent.
If you use an email list hosting service for your ezine, make sure you pick one that "strips" HTML emails. Then individuals can choose to receive "text only" emails from you even though you've sent out an HTML version. The service actually "strips" HTML codes and graphic codes from your email. Many services offer this stripping feature. However, in order to use it, you have to go to their site and register your email address. Then as part of registration process, they ask you to choose between text only and HTML.
There are services that will read information from subscribers and automatically set them up for HTML or text only emails based on what ISP (Internet Service Provider) or DSL (Digital Subscriber Line) service they use.

The secret about HTML ezines is that all graphics are linked from your website to your ezine and are not attached to your email. The problems with HTML ezines are...
~~ in order for your readers to see pictures you've placed in your message, they must be on Internet. ~~ they are not accessible and/or readable to some disabled individuals. ~~ people who have older email programs or computers can't read them. ~~ many libraries use computers that cannot handle graphics. ~~ they take up quite a bit of bandwidth (space) on someone's email server and they take longer to download than text messages. ~~ they take much longer to edit and publish. ~~ some people purposely set their email to not accept HTML mail. ~~ some people have their email set on text only - and don't know it! ~~ for AOL users, if size of file is more than 20K, it will be sent out as an attachment. ~~ many people won't open attachments
