Why this Step Matters

The purpose of cross-flow exclusion filters is to prevent someone from entering both the standard flow and the Upstack copy of the flow within a set timeframe. This avoids overlapping or duplicate messages, ensuring a smoother customer experience, reducing message fatigue, and keeping your reporting data clean.

​
Prerequisites

Before you start, you need:
  • The Klaviyo destination configured in Upstack Data
  • Existing standard abandonment flows in your Klaviyo account (Browse, Cart, Checkout, Site)
  • The Upstack copy of each abandonment flow already cloned and renamed with the - Upstack Data suffix (learn how)
  • Admin (manager) access to the store’s Klaviyo account
Key terms used below:
  • Standard flow → the original abandonment flow in your Klaviyo account (for example, Abandoned Cart).
  • Upstack copy of the flow → the cloned version triggered by Upstack Data’s *- Upstackified events, named with the - Upstack Data suffix (for example, Abandoned Cart - Upstack Data).

​
Part 1: Add the exclusion filter to the standard flow

  • Open the standard flow (for example, Abandoned Cart) in Klaviyo.
  • Click the Trigger card at the top of the flow.
Klaviyo flow editor with Trigger card selected at top of flow
  • Go to Profile filters and click Edit.
  • Scroll to the bottom of the existing profile filters and click + AND.
Profile filters section with Edit button and AND condition option
  • Select the condition: What someone has done (or not done).
  • Choose Person has → Received Email.
  • Set the count and timeframe: zero times → in the last 7 days (or 14 days if preferred).
  • Click Where and add: Flow equals the Upstack copy of this flow. For example: Flow equals Abandoned Cart - Upstack Data. Read as: Has received email 0 times in last 7 days where Flow = Abandoned Cart - Upstack Data.
  • Click Save.

​
Part 2: Add the reverse exclusion filter to the Upstack copy of the flow

  • Open the Upstack copy of the flow (for example, Abandoned Cart - Upstack Data) in Klaviyo.
  • Click the Trigger card at the top of the flow.

  • Go to Profile filters and click Edit.
  • Scroll to the bottom of the existing profile filters and click + AND.

  • Select the condition: What someone has done (or not done).
  • Choose Person has → Received Email.
  • Set the count and timeframe: zero times → in the last 7 days (or 14 days if preferred).
  • Click Where and add: Flow equals the standard flow. For example: Flow equals Abandoned Cart. Read as: Has received email 0 times in last 7 days where Flow = Abandoned Cart.
  • Click Save.
Reverse exclusion filter referencing the standard flow name

​
Part 3: Verify both filters are in place

  • On the standard flow trigger, confirm the profile filter references the Upstack copy name (for example, Abandoned Cart - Upstack Data).
  • On the Upstack copy of the flow trigger, confirm the profile filter references the standard flow name (for example, Abandoned Cart).
  • Spot-check a recipient profile after going live: confirm they only receive an email from one of the two flows within the 7-day window.
Done 🎉 Repeat both Part 1 and Part 2 for each abandonment flow pair: Cart, Browse, Site, and Checkout.For the full setup walkthrough, see How to set up your Upstack abandonment flows in Klaviyo.
