Help with Conditional Split comparing with dynamic variable (Product Saved → Placed Order)

Hi ,

I need help setting up a flow that prevents sending a reminder email if someone places an order for the same product they saved earlier.

Here’s my setup:

• Trigger metric: Product Saved

• Event properties example:

  { "sku_last_part": "5932", "product_name": "bird-8788491", "price": 12, "product_sku": "1105-5932", "pt_sub_id": "6" }

   

• Placed Order event example:

  { "order_total": 153.9, "sku_last_part": "5932", "product_names": ["bird-8788491"], "currency": "USD", "items": [ { "price": 12, "quantity": 12, "product_name": "bird-8788491", "product_sku": "1105-5932" } ], "order_id": "1", "product_skus": ["1105-5932"], "$value": 153.9 }

   

Goal:
If a customer saves a product (Product Saved event) and does not place an order (Placed Order event) with the same sku_last_part within 7 days, they should get a reminder email.
If they do place an order for that same product, the reminder email should be skipped.

Flow setup:

1. Trigger: When someone Product Saved

2. Wait: 8 minutes (for testing)

3. Conditional Split:

   • Has Placed Order at least once since starting this flow where sku_last_part equals {{ event.sku_last_part }}

   • YES → End (no reminder)

   • NO → Send reminder email

My questions:

1. How can I correctly compare sku_last_part from the Product Saved trigger with the sku_last_part from the Placed Order metric?

2. Is there a known limitation when using event properties from the trigger inside a Conditional Split filter?
