title: Send an email via MailChimp
body: <p>I think problem is around <code>$api-&gt;listSubscribers()</code>    </p>
  
  <pre><code>include('../libs/mailchimp/MCAPI.class.php');
  
  $options = array('list_id' =&gt; '$list_id', 'subject' =&gt; 'Prova', 'from_name' =&gt; 'name', 'from_email' =&gt; 'info@example.com');
  $content = array('html' =&gt; '&lt;p&gt;Testo di prova&lt;/p&gt;');
  
  $api = new MCAPI($apikey);
  $campaignId = $api-&gt;campaignCreate('trans', $options, $content);
  
  $api-&gt;listSubscribe($options['list_id']);
  
  $api-&gt;campaignSendNow($campaignId);
  
  if ($api-&gt;errorCode){
      echo "Unable to Create New Campaign!";
      echo "\n\tCode=".$api-&gt;errorCode;
      echo "\n\tMsg=".$api-&gt;errorMessage."\n";
  } else {
      echo "New Campaign ID:".$campaignId ."\n";
  }
  </code></pre>
