Each event is resolved to a person against a 750M+ device graph before it reaches Omnisend, so flows trigger on a known profile rather than an anonymous session.
How it flows
01 Capture
One Upstack app setup that captures Shopify storefront and checkout events with the Upstack Pixel, records every order directly from Shopify, and forwards both to every tool you spend on.

Every Shopify 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
customer_typeNew or returning, resolved before send.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
Resolved events and profiles into Omnisend for email and SMS automation.

Omnisend’s native Shopify integration only sees visitors Shopify has identified, typically logged-in customers or shoppers who entered an email at checkout. Upstack matches anonymous sessions to known customer profiles and sends browse, cart, checkout and purchase events to Omnisend with the contact’s email attached, so abandoned cart and browse abandonment workflows fire for many more visitors.
| From Shopify and Upstack | In Omnisend |
|---|---|
| Product views, add to carts, checkouts and orders Trackable activities that can trigger workflows. | Activities on the contact |
| The email Upstack resolved Added when the visitor is identified, which is what lets a workflow trigger. | Contact email |
| Other known properties Upstack can create or update the contact so it can be segmented and messaged. | Contact properties |
Omnisend receives events from Upstack’s servers only, so there’s no extra browser tag to manage.
If Omnisend’s Shopify integration sends the same event types, Omnisend may record both. Disable those events there and keep the native integration for anything Upstack doesn’t route.
Upstack attaches the contact’s email only when it identifies the visitor. Events from visitors it can’t match carry no contact for a workflow to reach.
The catch
Everything before that (the browse, the add to cart, the return visit four days later) is anonymous unless something resolves it. That is the gap the flows fall into, not a problem with the flows.
Omnisend Audience the contact's activity
and the automation's own trigger log.
What changes
Omnisend
Upstack sends events to Omnisend from its servers only, so ad blockers and browser privacy settings can’t block delivery.
Omnisend
Events sent to Omnisend carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.
Shopify
Purchases also reach Upstack directly from Shopify, about 10 minutes after the order, so an order still counts when an ad blocker stopped the pixel or the shopper closed the page.
Shopify
Shopify customer IDs, emails and phones are matched against the graph, so repeat buyers are identified across devices.
Setup
App install, no theme edits and no developer. You need admin access to your Omnisend account, with permission to create API keys and owner or staff access to Shopify.
01
In the Upstack dashboard, open System, then Data Sources, and click Connect Shopify. Approve the install in your Shopify Admin: Upstack reads products, orders and customers, and writes only its own pixel.
02
In Omnisend, open Store settings, API and create a key with permission to write events and contacts: typically a 64 character secret followed by a hyphen and a short identifier.
03
Under Destinations, click New Destination, choose Omnisend, paste the API key and click Create Configuration. It’s the only field the destination needs.
04
In Omnisend’s native Shopify integration, disable the event types Upstack now sends.
05
Add a product to cart on your store, then check the contact’s activity feed, or Audience and Reports, in Omnisend.
After setup
Upstack shows the Omnisend destination as Healthy.
Audience or Reports in Omnisend shows contacts and events from Upstack Data within a few minutes of a test purchase or page view.
The test contact’s activity feed shows the add to cart you made.
Troubleshooting
Both Upstack and Omnisend’s native integration send that event type. Disable it in the native integration.
Check the destination is Healthy and that the API key can write events and contacts. Upstack doesn’t need account management or billing permissions.
FAQ
Connect Shopify to Upstack, create an Omnisend API key under Store settings, API, and add it as the Omnisend destination. Then turn off the overlapping events in Omnisend’s native Shopify integration. Most brands are live in under 20 minutes.
Omnisend’s native integration only sees visitors Shopify has identified, typically logged-in customers or shoppers who entered an email at checkout. Upstack matches anonymous sessions to known customer profiles and sends those events to Omnisend with the contact’s email attached, so abandoned cart and browse abandonment workflows fire for many more visitors.
Possibly. Disable the corresponding events in Omnisend’s native integration for any event types Upstack sends, and keep the native integration only for events you are not routing through Upstack.
When Upstack identifies a visitor, it enriches the event with the contact’s email and any other known properties, and can create or update the contact in Omnisend.
Upstack marks the destination Healthy, and Audience or Reports in Omnisend shows contacts and events from Upstack Data, typically within a few minutes of a test purchase or page view.
No. Shopify connects as an app install with no theme edits, and most brands are live in under 20 minutes. Headless storefronts add the Upstack Pixel script instead of the theme app extension.
Permission to write events and contacts. Use the minimum scope: Upstack doesn’t need account management or billing permissions.
It can. When it identifies a visitor, Upstack can create or update the contact in Omnisend, so it can be segmented and messaged.
