🎯 How It Works

Example: Order Completed Email

1. WooCommerce fires hook:

   do_action('woocommerce_order_status_completed', $order_id, $order);
   

2. EmailManager catches it:

   public function send_order_completed_email($order_id, $order) {
       if (!$this->is_event_enabled('order_completed', 'email', 'customer')) {
           return; // Event disabled, skip
       }
       $this->send_email('order_completed', 'customer', $order);
   }
   

3. EmailRenderer renders:

   $template = TemplateProvider::get_template('order_completed', 'email');
   $variables = $this->get_variables('order_completed', $order);
   $content = $this->replace_variables($template['body'], $variables);
   $html = $this->render_html('modern.html', $content, $subject, $variables);
   

4. Email sent:

   wp_mail($customer_email, $subject, $html, $headers);
   

5. Customer receives beautiful HTML email! 🎉
