Schedule follow-ups and reminders from Shopify order events

When an order is placed, a fulfillment is delayed, or a return is filed in Shopify, MESA creates a Google Calendar event with the relevant details and assigns it to the right person. Your team never misses a follow-up because it lived in someone's head instead of their calendar.

Block time for fulfillment based on incoming order volume

When orders cross a volume threshold in Shopify, MESA creates a Google Calendar event to reserve fulfillment capacity for your team. Your schedule reflects the work that's actually coming without someone manually blocking time.

Trigger Shopify actions from Google Calendar events

When a scheduled event arrives — a sale launch, a product drop, a promotional window — MESA kicks off the corresponding action in Shopify. Your calendar becomes the trigger layer for your store, not just a reminder system.

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.
