Post-purchase Triggers for Klaviyo Flows
Your Klaviyo post-purchase flows are only as good as the events that trigger them. If 'Shipped' fires hours late or 'Delivered' never fires at all, your customers churn from confusion. Shipping events from our WMS flow into Klaviyo as they happen — Order Shipped, Out for Delivery, Delivered — so your flows hit at the right moment and review requests, replenishment nudges, and upsells convert.
What syncs automatically
Shipping and delivery events from our WMS flow into Klaviyo so your post-purchase flows actually fire on the right trigger.
Order Shipped event
Triggered when a label is generated and the order leaves our Paramount, CA warehouse. Fires your Klaviyo 'Shipped' flow.
Out for Delivery event
Triggered on carrier scan so 'arriving today' flows hit when the customer is actually expecting the parcel.
Delivered event
Triggered on the carrier's delivered scan so review request and post-delivery upsell flows fire at the right moment.
Order details
Tracking number, carrier, and shipping address push through to Klaviyo properties so flow content can deep-link or personalize.
Why brands using Klaviyo choose 3PLGuys
Accurate Shipped event timing
Most 3PLs send 'Shipped' on a batch sync hours after the fact. Our WMS fires the event the moment the label generates, so flows hit in real time.
Delivered events that actually fire
If your 'review request' flow waits 3 days after delivery but your 3PL never fires the Delivered event, those reviews never get asked. We push delivery scans through to Klaviyo as the carrier reports them.
Tracking page URL in every event
Branded tracking URL pushes as an event property so your Shipped email can deep-link customers to a branded tracking experience instead of a raw carrier site.
Compatible with Klaviyo flows you already built
We map our events to Klaviyo's standard names — Order Shipped, Out for Delivery, Order Delivered — so existing flows just start firing without flow rebuilds.
Profile property updates
Shipped count, last-shipped date, and lifetime parcel count push to customer profiles so you can segment on real fulfillment behavior.
Works alongside Shopify-to-Klaviyo
If you already use Shopify's Klaviyo connection for Placed Order and Fulfilled, we layer in the missing carrier-level events without conflicts.
How the integration works
Connect your Klaviyo account and ship within days, not months.
Connect Klaviyo to our WMS
Share your Klaviyo API key with our team. We configure the event mapping — Shipped, Out for Delivery, Delivered — to your account.
Map events to existing flows
Point your existing Shipped, Out for Delivery, and Delivered flows at the new events. If you do not have those flows yet, we share starter templates.
Flows fire on real fulfillment data
Orders ship, events push to Klaviyo in real time, flows trigger on accurate timing. Review requests land after actual delivery — not 3 days after a manual 'Shipped' click.
Built for Klaviyo sellers
DTC brands running review request flows
If your 'leave a review' email fires 3 days after Delivered, that event has to actually fire. We push it through reliably so review volume goes up.
Subscription brands with renewal nudges
Replenishment and renewal flows depend on knowing when the box actually arrived. Delivered events let you time the nudge to real consumption.
Brands testing post-purchase upsells
Cross-sell and upsell flows that fire on Shipped or Delivered convert better when timing is accurate. Late or missing events kill the funnel.
WISMO reduction programs
Proactive Shipped and Out for Delivery flows reduce 'where is my order' tickets — but only if the events fire on time. We make sure they do.
