title: PHP sending an HTML EMAIL Page from a website
body: <p>I've used PHP to send emails before but never to send a full HTML page from another source and so I'm wondering where to start and a few other things. </p>
  
  <p>I did a bit of research but my confusion isn't clearing up any.</p>
  
  <p>Do I directly get the web-page contents and send that or can I use a setting to just use a URL?
  What is the simplest method I could use and could someone show me an example?
  Are there risks with sending an email like this to say... 5000 people and how do I change the header data with a return link to URL source?</p>
