How it flows
How a Funnelish event reaches Klaviyo. Tracked on the funnel page, resolved to a person, then sent.
01 Capture
Captured from Funnelish
Add the Upstack Pixel to your Funnelish funnels to track what shoppers do there. When Funnelish creates the order in Shopify, Upstack records it like any other Shopify order.

02 Understand
Resolved to one person before it leaves
Every Funnelish event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.
How resolution works →
Resolved before it is sent - IdentityMatched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer.
customer_typeNew or returning, resolved before send.- DeduplicationOne order produces one event, so a single purchase cannot trigger the same flow twice.
- Bot and fraud filteringAutomated traffic never becomes a profile, so list quality and deliverability are not paying for it.
03 Activate
Delivered to Klaviyo
Attach re-identified emails to events before they reach Klaviyo, so browse and cart flows fire for people the pixel lost.

Which events reach Klaviyo
Each Upstack event is mapped to the Klaviyo event below before it is sent.
| Upstack event | Sent to Klaviyo as | Key data on the event |
| Product view | Viewed Product | ProductName, ProductID, Price, ImageURL |
| Add to cart | Added to Cart | ProductName, ProductID, Price, Quantity, CartValue |
| Checkout | Started Checkout | CartValue, ItemCount, CheckoutURL |
| Purchase | Placed Order | OrderID, Revenue, Items, DiscountCodes |
Upstack’s identity resolution attaches the visitor’s email before an event is forwarded, and syncs profile properties ($first_name, $last_name, $city, $region) plus custom identity properties to Klaviyo.
The catch
Funnel pages sit outside your Shopify theme, so storefront tracking never sees the visit that led to the order.
With the Upstack Pixel on each funnel, the funnel visit and the Shopify order Funnelish creates resolve against the same graph as the rest of your store.

The event appears as its own metric, and the profile count on it is the number you were losing before.
What changes
What changes when Funnelish feeds Klaviyo. Two gains on the Klaviyo side, two on the Funnelish side.
Klaviyo
Recover carts you couldn’t email
Anonymous browsers are resolved to a known profile, so abandonment flows can trigger for visitors Klaviyo never identified.
Klaviyo
Profiles, not sessions
Events arrive attached to a resolved customer, so flow logic and segmentation work on a person.
Funnelish
Funnel pages tracked
The pixel loads in the head of every funnel page, so visits and the events you configure are recorded on pages your theme never touches.
