title: Iframe doesn't appear on Mailchimp newsletter campaign
body: <p>I am looking for some help with my Mailchimp newsletter campaign so that codes like:</p>
  
  <pre><code>&lt;iframe src="http://www.bridgebase.com/tools/handviewer.html?k=s&amp;s=sk32hqj865dcqt542&amp;d=e&amp;v=b&amp;a=1s?" height="300px" width="200px"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>or a poll from ch as:</p>
  
  <pre><code>&lt;script type="text/javascript" charset="utf-8" src="http://static.polldaddy.com/p/7690662.js"&gt;&lt;/script&gt;
  &lt;noscript&gt;&lt;a href="http://polldaddy.com/poll/7690662/"&gt;Wat bid je?&lt;/a&gt;&lt;/noscript&gt;
  </code></pre>
  
  <p>Will actually show in the newsletter. I only get to see them in the preview page but once the campaign is sent the info disappears.</p>
