If you want to revert a template to Shopify's original design:

1. Go to [Shopify Admin → Settings → Notifications](https://admin.shopify.com/settings/notifications)
2. Click on the template you want to revert
3. Click **Revert to default**

This removes the Smart Emails code and restores Shopify's built-in template. You can re-export from Smart Emails anytime to apply your design again.
