title: Mailgun template for batch sending with recipient variables in Handlebars expression
body: <p>I am trying to create a Mailgun template for batch sending, and the template needs to use a <strong>recipient variable</strong> within a <strong>Handlebars</strong> conditional to determine the language to use, like so:</p>
  
  <pre><code>&lt;div&gt;
    {{#if %recipient.eng%}}
      Hello
    {{else}}
       Bonjour
    {{/if}}
  &lt;/div&gt;
  </code></pre>
  
  <p>However, when making a POST call to create the above template, I get the error response:</p>
  
  <pre><code> "message": "template parse error: Parse error on line 2:\nLexer error\nToken: Error{\"Unexpected character in expression: '%'\"}"
  </code></pre>
  
  <p>There isn't any documentation on the Mailgun site that uses batch sending with Handlebars, so it may not be possible.<br>
  Has anyone managed to successfully do this?</p>
