Email is your highest-ROI channel. But if your Shopify mobile app is not connected to Klaviyo, you are leaving most of that revenue on the table.
Here is the problem most UK brands hit: they launch a mobile app, customers start browsing and adding to cart on the app, but the abandoned cart emails never fire. The app events are not flowing into Klaviyo. The segments are stale. The flows are only picking up web sessions.
Why Klaviyo plus mobile app integration matters
Klaviyo works brilliantly for web. But mobile apps behave differently. Customers browse on the app, do not convert, close it. If your Klaviyo flows only track web events, those sessions are invisible.
When you properly connect your Shopify mobile app to Klaviyo:
Abandoned cart flows fire based on in-app sessions, not just web visits. Customer profiles update with mobile behaviour data. You can segment by app users vs web users and test different messaging. Push notifications and email work in tandem rather than in isolation.
The events to track
Your Shopify mobile app fires events when customers take actions. These events need to flow into Klaviyo the same way web events do.
The key events to track from the app: Active on site (mobile version) so browse abandonment flows can fire. Viewed product to power personalised recommendation emails. Added to cart for abandoned cart flows. Started checkout for checkout abandonment. Placed order so post-purchase flows and loyalty programmes work correctly.
Setting up the integration
At Talmee, we build custom Shopify mobile apps for UK ecommerce brands. Every app we ship includes a full Klaviyo integration by default.
The integration process: Add your Klaviyo API key to the app configuration. Map customer identifiers so mobile events merge into the correct Klaviyo profile. Fire the standard Klaviyo events from the app using Klaviyo's track API in the same format as the web pixel. Test the flows end to end before going live.
Segments that unlock once it is live
Once mobile events are flowing into Klaviyo, these segments become available: High-value mobile users who have placed multiple orders via the app. App-only browsers who consistently browse on the app but purchase on web. Lapsed app users who were active more than 60 days ago. Push opted-in and email active customers, your most reachable segment.
Push and email working together
The real unlock is coordinated push and email campaigns. Send an abandoned cart push one hour after the event. If they do not convert, send a Klaviyo abandoned cart email three hours later. If still no purchase, send a push with a time-limited discount the next morning.
This kind of sequenced messaging based on actual customer behaviour is what separates high-performing DTC brands from the ones just blasting newsletters.
If you are a UK Shopify brand looking to launch a mobile app with a proper Klaviyo integration built in from day one, Talmee builds exactly that. Based in Manchester, we have helped brands across fashion, beauty, homewares, and food launch fully integrated mobile apps.
