Boilerplate may not be the best word... I would have called it "skeleton code" or something along those lines. And the answer to your question is right there in the big box on the site: "This website and its sample code creates a template of sorts, absent of design or layout ...". So, no, it doesn't look like the website or much of anything at all save for a sample line of text, a sample image, and a sample table... all of which you'd delete and replace with the style and content you wish your email to have.
