title: How can I add a signature into an Outlook email with JavaScript mailto?
body: <p>I am using JavaScript mailto function to fill an email body with custom text.</p>
  
  <p>I can add text to the email but the signature doesn't show up.</p>
  
  <p>Is there any way to send a custom signature with an image using mail-to function?
  Or is there any way to insert an HTML image in the body when using the mail-to function?</p>
  
  <p>Sample code:</p>
  
  <pre class="lang-vb prettyprint-override"><code>var message = "text of message";                
  var mailLInk = "mailto:sam@example.com?subject=subject&amp;body=" + message;        
  document.location.href = mailLink;
  </code></pre>
