Why integrate Email with Square

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

Trigger customer alerts the moment something changes

When a Shopify event fires, MESA sends a targeted email to the right person — customer, teammate, or vendor — with order details, tracking info, or status updates pulled directly from the workflow.

Turn inbound emails into workflow triggers

Every email sent to your custom MESA address becomes a workflow trigger. Subject line, sender, and message body pass through as variables, so you can route, log, or respond to inbound email automatically.

Send personalized transactional emails at scale

Each email MESA sends can include customer names, order details, and product data pulled directly from the workflow. Recipients get accurate, relevant communication without any manual drafting.

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.

Build any Email and Square 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.
