They need to be set in **Transactional Related Data** first. - Save user order details under **Transactional Related Data** and send order email (with additional parameters): choose **message_id** of the prepared message and use order details to present order details. Additional data can be added as parameters and used in email templates. Save your zap and turn it on to go live!
