Why integrate Klaviyo with ShipStation

The Klaviyo to ShipStation integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.

Data integration →

Keep Klaviyo profiles current as customers shop

When a customer's behavior changes in Shopify — a new purchase, a tag update, a loyalty tier change — MESA updates their Klaviyo profile in real time. Your segments and flows always reflect who your customers are right now.

Customer experience →

Trigger Klaviyo flows from any Shopify event

When an order is placed, a subscription starts, or a customer hits a milestone, MESA sends the signal to Klaviyo and starts the right flow. Your email automation runs on the full range of what happens in your store, not just native Shopify triggers.

Order automation →

Suppress the right customers from campaigns automatically

When a customer files a return, opens a support ticket, or enters a sensitive window, MESA updates their Klaviyo suppression list or profile status. Your campaigns reach the right people at the right time without manual list hygiene.

Fulfillment operations →

Push every Shopify order to ShipStation the moment it's placed

When an order comes in, MESA sends it to ShipStation with the right shipping method, carrier, and fulfillment rules already applied. Your team picks up a ready-to-ship order, not a configuration task.

Order automation →

Route orders to the right warehouse based on what's in the cart

When an order contains specific products, a wholesale flag, or a regional destination, MESA reads the details and sends it to the correct ShipStation fulfillment location. Every order reaches the right facility without manual sorting.

Customer experience →

Update Shopify the moment ShipStation marks an order shipped

When ShipStation generates a tracking number and marks an order fulfilled, MESA writes the update back to Shopify and triggers any downstream actions — a Klaviyo notification, a customer tag, a loyalty point. Your post-purchase workflow starts the moment fulfillment does.

Build any Klaviyo and ShipStation automation

MESA helps you connect apps to automate repetitive tasks. A trigger is an event that starts a workflow, and actions are the steps that occur when it's running.
