Add Instagram subscribers to Shopify as customers automatically

When a follower subscribes through a Gatsby Instagram campaign, MESA creates or updates their record in Shopify. Your store knows about the customer from the moment they raise their hand on Instagram, before they ever place an order.

Trigger a welcome flow the moment someone subscribes via Instagram

When a new subscriber joins through a Gatsby DM campaign, MESA sends the signal to Klaviyo and starts the right onboarding sequence. Your first impression lands while the engagement is still warm, not after a sync cycle.

Tag Shopify customers based on which Gatsby campaign acquired them

When a subscriber joins through a specific Gatsby campaign — a giveaway, a product launch, a keyword trigger — MESA applies the corresponding Shopify tag to their customer record. Your segments reflect how each customer was acquired without anyone managing attribution manually.

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.
