How to Use Klaviyo Segments to Target Visitors in an Intelligems Test or Personalization

What you can do with Klaviyo

Use a Klaviyo segment (like VIP customers) to control who sees a specific Test or Personalization in Intelligems.

How it Works

1. When a visitor is cookied by Klaviyo we use that cookie (_kx) to “ask” Klaviyo: “Which segments is this visitor

2. If Klaviyo is able to identify the visitor (i.e. they completed a signup flow, clicked through an email/sms, returned to a site from a browser they previously made a purchase, etc.) then so is Intelligems.

If we're unable to identify the visitor, they will be shown the control / not enter the experience.

Common Use Cases

• Past purchasers (e.g., a Klaviyo "Customers" segment) — this is the recommended way to run customer-only tests, since Intelligems does not natively have access to Shopify purchase history

• VIP and Loyalty customers

• Email subscribers or segment-specific cohorts (e.g., cart abandoners, active shoppers)

Why This is Better Targeting Than Using UTMs

1. Does not require clickthrough - They do not have to click through a Klaviyo email in order for this targeting to work, it’s based on their cookies (which could have been previously set).

2. Cross-device segment targeting - If the visitor later opens up a Klaviyo email on a different device and/or visits the website and logs in, we will now have the ability to target the new browser/device (cookie) and can serve up cross-device experiences. Each device receives a new igId, but experiences remain consistent through Klaviyo segment membership, not a shared ID.

Prerequisites

• Intelligems is installed on your store

• Klaviyo is installed and set up. Install here.

• You have at least one Klaviyo segment (e.g. “VIP”)

Step 1: Connect Klaviyo to Intelligems

1. In Intelligems, on the left navigation, click on Integrations

2. Find Klaviyo under Analytics

3. Click Sign in with Klaviyo

4. Log in if prompted

5. Approve permissions (profiles + segments)

6. Confirm Klaviyo shows as Active in the Intelligems integrations page.

Step 2: Confirm Your Segment in Klaviyo

1. Open Klaviyo

2. Go to Lists & Segments

3. Confirm the Segment you want to target (e.g. VIP) exists

We can only identify visitors in Segments. We cannot identify visitors in Lists or using Profile Tags.

1. Optional Send yourself an email so your profile is tagged with that Segment

We recommend you star/favorite Segments inside of Klaviyo that are active in a Test or Personalization

Step 3: Apply the Segment to a Test or Personalization

1. Create a Test or Personalization in Intelligems

2. Go to the Targeting tab

3. Select Custom

4. In the Targeting type dropdown, select Klaviyo Segment

1. Add a condition Klaviyo segment equals VIP

To add multiple Segments, use the +Or Condition and +AND Condition option

1. Click Save

For Tests, use Advanced, not Custom Targeting, if you want to avoid default assignment. Otherwise, users may get a default variation first and never switch when the segment is detected.

Step 4: Verify It’s Working

1. Open the Klaviyo email you sent

2. Click the link to your store

3. Watch the URL — you should see a Klaviyo cookie parameter

4. The page may load the default first, then update

5. Confirm the correct experience appears (e.g. your personalized discount appears)

Result

Users in the targeted Klaviyo segment see the intended Intelligems variation automatically 🎯

FAQs

Does Intelligems receive customer profile data from Klaviyo?

No. Only segment membership is resolved via exchange ID.

Is segment membership evaluated in real time?

Segment membership is resolved on visit and cached for up to 1 hour.

Does this work across devices?

Yes, if the visitor clicks a Klaviyo link on each device or logs into that store. Each visitor receives a new igId on each device, but experiences remain consistent because targeting is based on Klaviyo segment membership, not a shared ID. If Klaviyo is able to identify the visitor, then so is Intelligems.

Does this work with Klaviyo lists?

No, this is only for Segments.

Does this read Klaviyo profile tags?

No, this is only for Segments.
