How can I download a list of customers in the waitlist of my back in stock flow?
You can create a segment to pull in the users and export the segment. The segment conditions you'll want to use are:
1. What someone has done (or not done)
- Has Subscribed to Back in Stock at least once over all time
2. What someone has done (or not done)
- Has Received Email zero times over all time, Where flow equals [Back in stock flow ID]
