+### Using Creation Object Reference
+
+The Smartmail constructor accepts a generic type parameter that lets you associate any additional data with your email, accessible later via the `getCreationObject()` method. This is useful for tracking, referencing original data sources, or maintaining context:
+
+```typescript
+// Define your custom reference type
+interface OrderNotification {
+  orderId: string;
+  customerName: string;
+  items: string[];
+  total: number;
+}
+
+// Create email with typed creation object reference
+const orderEmail = new Smartmail<OrderNotification>({
+  from: 'orders@example.com',
+  to: ['customer@example.com'],
+  subject: 'Your Order #{{orderId}} Confirmation',
+  body: 'Thank you for your order, {{customerName}}!',
+  // Store the full order data as reference
+  creationObjectRef: {
+    orderId: '12345',
+    customerName: 'John Smith',
+    items: ['Product A', 'Product B'],
+    total: 99.95
+  }
+});
+
+// Later, retrieve the original reference data
+const orderData = orderEmail.getCreationObject();
+console.log(`Processing email for order ${orderData.orderId}`);
+console.log(`Order total: $${orderData.total}`);
+
+// Use the reference data for templating
+const subject = orderEmail.getSubject(orderData);  // "Your Order #12345 Confirmation"
+const body = orderEmail.getBody(orderData);        // "Thank you for your order, John Smith!"
+```
+
+This powerful feature allows you to:
+- Maintain a link to original data sources
+- Pass the email object between systems while preserving context
+- Avoid duplicating data between email content and your application
+- Use the reference data to fill template variables
+- Access metadata about the email that doesn't get included in the actual message
