Hello,
is it possible to use the Reminder Rule - Unpaid Orders in combination with the orders payment method?
We have two payment methods configured, one that has to pay before the products are shipped and one that has to pay when the products arrive at the customers place.
So for the first payment method we won't send out an payment reminder email, but for the second payment method we need to send out a reminder after a couple of days.
Furthermore we would need to send out the email 30 days after the shippment was received by the customer.
Is this possible?
