title: Alternative to 0px images (aka web beacons)
body: <p>Our marketing department sends out a newsletter to 'opt-in' customers and would like to track how many of these emails were opened. This is NOT a spamming exercise - these clients can unsubscribe at any time and they opt-in to begin with. </p>
  
  <p>The problem is that many (most?) web and desktop email clients do not show images by default. This means that we can't tell if a user has opened an email as the 0px image does not fire. Of course if they allow images for our domain it will fire just fine. Here is some example code: </p>
  
  <pre><code>&lt;img src ="http://www.mydomain.com/?someInfo=x&amp;otherInfo=y" width="1" height="1" /&gt;
  </code></pre>
  
  <p>Does anyone know if there is any alternative to this method of tracking emails that are opened etc? </p>
  
  <p>Many thanks!</p>
