I have this enabled to be sent, however it seems if a client doesn’t have their credit card added, or an ACH payment method on file for whatever reason; this email isn’t sent? Even though it then appears on the clients profile that they have an outstanding balance. What am I missing? 

I also notice that for other notifications if its charged to their account balance (they are in the negative) it says “thank you for your purchase” I think this is extremely confusing because it insinuates that they don’t have an outstanding balance. How do I have things set up to notify a client if their account is in the red clearly. And not say thank you when they owe…
