title: Strike-through in HTML Emails
body: <p>I'm currently coding an HTML email, using MailChimp to test it, and eventually to send it.</p>
  
  <p>The email advertises several sales, which are displayed using the HTML <code>strike</code> tag. For some reason, these <code>strike</code> tags are not coming through to the finished test emails.</p>
  
  <p>Code as it appears in MailChimp:</p>
  
  <pre><code>&lt;strike&gt;$12.95&lt;/strike&gt; SALE! $9.95
  </code></pre>
  
  <p>Code in the test email, retrieved using Chrome Web Tools:</p>
  
  <pre><code>$12.95 SALE! $9.95
  </code></pre>
  
  <p>I've personally verified that this is happening in Gmail, Outlook 2007, and Yahoo! Mail. A quick perusal of my MailChimp Inbox Inspector results tells me the problem is definitely not limited to these three.</p>
  
  <p>Any idea why this might be happening? Is there a more reliable alternative I could use without resorting to images?</p>
