I know how to select the open, unfilled orders and then for instance batchprint packinglists and such. Also filtering the customer list is known to me.
But is it also possible to select only those customers who have placed an order that is still open (not fulfilled) and to send them an e-mail, or a message via Shopify marketing campaign. I would like to send all of them the same message, so I want to avoid contacting them one at a time. Would save a lot of time and work. It seems that there is no filter for selecting customers with open orders in the customer section.
