Why integrate Klaviyo with Mailgun

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

Data integration →

Keep Klaviyo profiles current as customers shop

When a customer's behavior changes in Shopify — a new purchase, a tag update, a loyalty tier change — MESA updates their Klaviyo profile in real time. Your segments and flows always reflect who your customers are right now.

Customer experience →

Trigger Klaviyo flows from any Shopify event

When an order is placed, a subscription starts, or a customer hits a milestone, MESA sends the signal to Klaviyo and starts the right flow. Your email automation runs on the full range of what happens in your store, not just native Shopify triggers.

Order automation →

Suppress the right customers from campaigns automatically

When a customer files a return, opens a support ticket, or enters a sensitive window, MESA updates their Klaviyo suppression list or profile status. Your campaigns reach the right people at the right time without manual list hygiene.

Order automation →

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.

Customer experience →

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.

Fulfillment operations →

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.
