Notification not delivering HTML version of email.

Hi,

I've been trying to figure this out on my own, but I'm having a hard time. I'm trying to see is there anything additional necessary in my php to send a FULL-HTML enabled email.

I do have the setting inside text-format set to Full HTML.

Here is my script:

$message = message_create('order_confirmation_message', array ( 'uid' => $commerce_order->uid) );
$wrapper = entity_metadata_wrapper('message', $message);
$wrapper->field_order_id_ref->set($commerce_order);
$wrapper->field_e_mail_subject->set("Make your appointment at Luhu");
message_notify_send_message ( $message );
