One Flow, for all Signups

In Chatarmin you can create ONE Flow with the Trigger “Signed up for ‘Back in Stock’”: Chatarmin help center image For all new Signups, the flow adds a Tag about the Product to their profile. A Tag with the label “BIS / Product X” -> Whereas “Product X” is the product/variant name So now you can even filter your audience based on that Tags

One Flow, for all ‘Back in Stock’ Products

Exactly for that, we have that unique Tag from their previous signup (mentioned above) Chatarmin help center image You can also customize when the Back in Stock notification is triggered, specifically in terms of the quantity of products that need to be back in stock before the notification is sent. You can adjust the settings in the Back in Stock flow so that the notification is only triggered when the stock level reaches a minimum threshold (e.g., 500 units). This ensures that the notification is sent only when there are enough items available, preventing messages from being sent prematurely due to small restocks (like a single returned item).

So you can for example set the Image for a template like so: Chatarmin help center image
