The above merge tags will display "No Donated Items" or " No Purchases or Cash Donations" if user did not donate/purchase. If you are intent on sending a custom template containing both donor and guest merge tags, be sure to send test emails to users with only purchases or only donations to make sure the placeholder message(s) displays coherently with your text/formatting.
