title: Testing HTML email rendering
body: <p>Are there any good tools to easily test how HTML email will look across different email clients? I prefer something with instant feed back rather than a submit and wait service like <a href="http://litmusapp.com" rel="noreferrer">http://litmusapp.com</a> Or at the very least a way to test the Outlook 2007/MS Word rendering?</p>
  
  <p>I found this related question but it doesn't specifically address testing. <a href="https://stackoverflow.com/questions/127498/what-guidelines-for-html-email-design-are-there">What guidelines for HTML email design are there?</a></p>
