We’ve just started building out more flows as a brand, some of which are quite lengthy but important content for us customers. I don't want to now start bombarding our customers with these flows as well as our normal trade sends which we do roughly twice a week, but sometimes more during sale times.
How can I set my flow, or adjust my trade segment, to only send to customers that aren't currently at a specific stage in a flow, or in a flow at all?
