Polar's Klaviyo Flows Enricher captures abandoned shoppers that Klaviyo's own tracking misses, and enrolls them in a duplicate flow — so you send more abandonment emails without any extra work.
​
​Requires: Shopify, Klaviyo, and Polar Pixel.

Browser privacy restrictions — like Safari's ITP, which caps first-party tracking cookies to as little as 7 days — can cause Klaviyo's cookie-based tracking to lose track of a returning visitor before they come back to browse, add to cart, or check out. Polar's Pixel adds server-side tracking, which helps catch many of the events that get missed this way. Our identity resolution engine matches what it can back to an email address, and enrolls that visitor in a duplicate flow — created in draft, so nothing sends until you review it.

TLDR: The best way to understand the feature is to watch Charbel, Polar’s CTO, in this short video:

These three metrics are what power your duplicate ("Polar") flows — each maps to one abandonment flow type.

While the setup is easy, we know your time is valuable, so the Polar team is happy to complete these steps for you or with you.

No need to remove your existing tool — Polar duplicates flows and you choose the send order.

Once everything is up and running, there are two ways to monitor the performance of the new Klaviyo flow.

This is usually caused by the email template pulling a dynamic variable under a different name than what's in the underlying event payload — most often after a flow has been duplicated or edited. This is exactly why we leave new flows in Draft: it gives you a chance to review the email and catch this kind of mismatch before anything goes live.

To fix it, open the Polar metric event in Klaviyo (under Metrics) and check the actual property names in the payload, then update the template's variable references to match.

Klaviyo treats price as a numeric value rather than a string in this context, so a currency symbol can't be included automatically. This is expected behavior today. If it would be valuable for your flows, let us know and we're happy to log it as a feature request.

This event can fire multiple times during a single checkout session as a shopper moves through checkout — contact info, shipping, payment. Typically, only one of those events contains the full product and cart details; the others include the checkout value but no line items. This is expected. A flow won't send an email if the event it's tied to doesn't contain the required cart data.

If a customer enters your native Shopify abandoned-checkout flow first, they won't also enter the Polar flow — this is intentional, and prevents the same customer from getting two emails for the same abandoned checkout.

Flow emails show the price captured by the Polar Pixel in real time, at the moment a shopper viewed, added to cart, or checked out — not a synced product catalog. Only events that fire after your price change will reflect the new price; anything that already fired will keep the price shown at that moment. Your native Shopify flows do a live catalog lookup at send time, which is why those update immediately.

This is usually a temporary sync delay in Polar's reporting pipeline rather than an issue with the Enricher itself — the Enricher can keep sending emails normally even while the Activate dashboard is delayed in reflecting results. If it persists for more than a day or two, reach out to Support and we'll take a look.
