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 icon

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.

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.

Process every line item in an order individually

When an order arrives with multiple products, Loop goes through each line item one at a time — tagging, routing, or syncing each to a downstream system based on its specific data. One order, many targeted actions.

Inventory management icon

Update each product in a batch file one by one

When a CSV or FTP file contains multiple products, Loop processes each row individually — updating prices, inventory levels, or descriptions in Shopify without treating the whole file as one action.

Fulfillment operations icon

Route each item to the right fulfillment location

For orders that split across multiple warehouses or vendors, Loop goes through each line item and sends the correct fulfillment request to the right destination. Every item reaches the right place.
