Ensure the Customer Checkout Online Order AutoResponder is active and configured as described in Order Drafts Configuration
Use a Test Customer under a Test Rep to ensure Bonus will not be affected for a live user. Change the Customer's email to an email you have access to in order to verify the email sent correctly and has proper formatting and function.
Create an Order Draft using the steps corresponding to the Order Draft Version in use described within Order Drafts and send the Order Draft to the Test Customer. After a few minutes, you should recieve an email with the link to Checkout with the Order that was created. Verify the Cart sent in the email matches the one created in Step 2.
Once you are in Checkout, be sure not to navigate back to the Shopping Cart. If a customer does so, they will not be able to proceed with the order draft that was created for them. A new Cart session will begin for the customer.
