title: Including a mailto url with subject and body that will open in Gmail/Mailbox apps
body: <p>I'm kind of baffled that this mailto url successfully opens a new email appropriately filled out on the iOS mail app, but fails to open anything at all when clicked on in the Gmail and Mailbox apps (most up to date versions):</p>
  
  <pre><code>&lt;a href="mailto:email@address.com?subject=This is the subject&amp;body=This is the body"&gt;link&lt;/a&gt;
  </code></pre>
  
  <p>Any ideas around how to get this mailto url to open in Gmail/Mailbox iOS apps as it does in the standard iOS mail app? Thanks.</p>
