  <p>I am sending html email (code like above) but mail appers incorrect in gmail.com and outlook.com. Both of them adds p tag around the a tag and span tag arround the img tag like this ;</p>
  
  <pre><code>&lt;td&gt;
    &lt;p class="some class name"
      &lt;a href="http://www.google.com" target="_blank"&gt;
        &lt;span class="some class name"&gt;
          &lt;img src="images/img_10.png" alt="" style="display:block;" width="600" height="31" border="0" /&gt;
        &lt;/span&gt; 
      &lt;/a&gt;
    &lt;/p&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>and so looks gap between tr tags. How can I solve this?</p>
