Online checkout - configuring receipt email sent to customer

[BenefitsLink]

How do I configure the email sent to a customer after they submit payment?

The subject line and body of the automatic email say "your items have been shipped". This is confusing our customers -- we don't ship anything, we're using Square online checkout to allow customers to submit payment for our online services (job ads posted on our website). 

I can't seem to find anything in the Dashboard that allows me to configure that email.  What am I missing?

You can change the product type from physical to digital and it should fix that.
