Why integrate Mailgun with Square
The Mailgun to Square integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.
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.
Sync Square transactions into your Shopify customer records
When a purchase is made in Square — in-store, at an event, at a pop-up — MESA creates or updates the customer's record in Shopify. Your ecommerce and physical sales channels share a single view of every customer.
Keep inventory accurate across Square and Shopify
When a sale is made in Square, MESA updates the corresponding stock level in Shopify. Your online storefront reflects what was just sold in person without a manual sync between your point-of-sale and your store.
Trigger post-purchase workflows from Square transactions
When a customer buys in Square, MESA kicks off the right next step in Shopify — adding a tag, enrolling them in a Klaviyo flow, updating a loyalty record. Your in-person sales feed the same automation as your online ones.
