Send transactional emails from Shopify order events automatically

When an order is placed, updated, or fulfilled in Shopify, MESA triggers the right Mailgun transactional email with the relevant details already populated. Your customers get accurate, timely messages without anyone manually initiating them or maintaining a separate send schedule.

Trigger Mailgun emails from any Shopify customer milestone

When a customer hits a threshold in Shopify — a first purchase, a loyalty tier, a win-back window — MESA sends the signal to Mailgun and fires the right email at the right moment. Your transactional and lifecycle messaging runs on the full range of what happens in your store, not just native Shopify triggers.

Send fulfillment and shipping notifications the moment status changes

When an order ships, is delayed, or is delivered in Shopify, MESA passes the event to Mailgun and fires the corresponding email at the right moment. Your post-purchase communication stays accurate and timely without custom development connecting the two platforms.

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.

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.

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.
