You can get many people who 'know Dreamweaver' or any other WYSIWYG. I prefer to do all the programming myself in a text editor. Because of this, I know all the code in my head - and in a bind I could work in Notepad if I had to. The following is an example of an html email newsletter that a client built in house with Dreamweaver. The email was displaying horribly in certain email programs.
WYSIWYG
Site building programs for the most part create really sloppy code. They're bloated, take longer to load, execute slower, are full of errors, and are hard for a human to read later to make modifications. The validation errors often create problems when viewing the web page in some browsers.

Hand Code
By creating code by hand, we have control over it. I create really clean code. The file size is smaller, loads faster, execute quicker, have zero errors, and is easy for a human to read later to make modifications. The validated code is problem free when viewing in every browser, including emailed newsletters.
