Postscript

Send Funnelish funnel events to Postscript

Q: How do I check that Funnelish events are reaching Postscript?

Open Postscript › Subscribers › the individual subscriber's activity feed.

Q: Can one purchase trigger the same flow twice?

No. One order produces one event, so a single purchase cannot trigger the same flow twice.

Q: How long does it take to connect Funnelish to Postscript?

Most brands are live in under 20 minutes. Once Funnelish events reach Upstack, every destination receives the same resolved events, Postscript included.

Each event is resolved to a person against a 750M+ device graph before it reaches Postscript, so flows trigger on a known profile rather than an anonymous session.

How it flows

How a Funnelish event reaches Postscript. 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.

Messaging mistakes are expensive and public. These controls exist so a flow never fires against a profile that should not have received it.

03 Activate

Delivered to Postscript

Send identity-resolved events to Postscript so SMS flows reach subscribers the pixel missed.

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.

What changes

What changes when Funnelish feeds Postscript. Two gains on the Postscript side, two on the Funnelish side.

Postscript

Server-side delivery

Events reach Postscript through its server API rather than the browser, so ad blockers and ITP don’t cost you conversions.

Postscript

Identity-resolved events

Events sent to Postscript carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.

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.
