The Zen Cart order confirmation email transmits the most important data about the order to your customers - but misses an important upselling opportunity. You have their attention - why not take advantage of that?

Order Message allows you to easily add a message to your order confirmation emails - HTML and plain text.

Here's an example of how the emails with the Order Message mod installed will look:

Order Message in Zen Cart HTML Email

The HTML message can be styled by modifying email/email_common.css. For example, if you add
.order_message {background-color:#E4E8F3; border:1px solid #9a9a9a; margin-top:3px; padding: 10px;}
Then the message would look like this:

Installation Instructions:

Note: For Zen Cart 1.5.6 and above, please omit step 3; this logic is already built in.
Before starting, back up everything! Try this in a test environment prior to installing it on a live shop.
  1. Unzip the file you have received. Rename any folder named "custom" to your template name.
  2. Set the define EMAIL_ORDER_MESSAGE in ./includes/languages/english/YOUR_TEMPLATE/email_extras.php to the desired message. Note that there is only one message for both HTML and plain text messages, so don't rely on embedded HTML.
    // DO NOT DO THIS:
      define('EMAIL_ORDER_MESSAGE','Thank you for your order!  For more fantastic deals, please <a href="http://www.example.com/signup.php">sign up for our newsletter</a>.');

      define('EMAIL_ORDER_MESSAGE','Thank you for your order!  For more fantastic deals, please sign up for our newsletter at <a href="http://www.example.com/signup.php">http://www.example.com/signup.php</a>.');
  3. In includes/classes/order.php, search for
        // include disclaimer
    above this, paste in these lines of code:
        // Add in store specific order message
        if (defined('EMAIL_ORDER_MESSAGE')) { 
        $this->email_order_message = EMAIL_ORDER_MESSAGE; 
        if (!empty($this->email_order_message)) { 
          $email_order .= "\n\n" . $this->email_order_message . "\n\n";
        $html_msg['EMAIL_ORDER_MESSAGE'] = $this->email_order_message;
  4. Copy the contents of the includes folder to the includes directory of your shop.
  5. Place a test order in your store to test these changes.
