By testing this issue, you've sent real customers a double reminder today at 5:37pm today... Please be very careful when testing not to send anything to our customers.
All Contacts info is now real. => you should test in the testing environment. If you want to test/edit anything in our live production please do this together with David but not independently.
We are lucky there were only 3 customers who didn't pay yet; I had to send them a personal apology email.
