The entire HTML is copied and sent by email along with the images
(images are integrated in the email so they will always be shown, no need for your reader to click on "Display Images below").
To try this tool, you can reuse this example of Newsletter (simply past the url in the app): https://sites.google.com/site/scriptsexamples/available-web-apps/newsletter-creator/newsletter-1
If you create a Google Sites page with the 3-column layout, your page will be beautified when sent as a newsletter (a little border will be added, text will be justified, images will fit better,...)
