Connect API to Email and automate your tasks

Why integrate API with Email

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

Pull live data into any Shopify workflow

When an order fires, MESA calls an external API and brings the response in as variables. Pricing feeds, fraud scores, or inventory levels from any service become available to every step that follows.

Send order details to your internal systems

MESA posts Shopify order data to your internal API or ERP the moment an order is created. Your operations and fulfillment tools stay current without custom middleware or manual exports.

Enrich orders with third-party data at checkout

MESA calls an external API at the moment of purchase — pulling fraud signals, shipping rates, or tax data — and uses the response to route or update the order before fulfillment starts.

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.

Build any API and Email 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.
