How can I remove subscribers from a Back In Stock list?

Hi @Chris-J!

One way you could opt-out the existing customers is to create a new List of all the profiles that you want to exclude from a flow, and then use a flow filter or conditional split to remove them. Our Community Champion Joe discusses this here:

After you create a List, perhaps called “BackInStock_Exclude” or something to that effect, you’d simply go to your Back in Stock flow and add a flow filter by clicking on the trigger and selecting the Flow Filters option. Then, add a new flow filter that checks to ensure profiles are not in the BackInStock_Exclude list:

Since flow filters are checked before each step of the flow, this would accomplish your use case. You could also use a conditional split, if you’d prefer that customers are exited at a specific step in the flow.

I hope this helps, and thanks for using the Community!
