Why teams connect Insightly and Klaviyo

Sync what happens in Klaviyo with the customer records in Insightly, in real time and in both directions.

Whatever Klaviyo holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Flows, Templates, Catalog Items, Tags in Klaviyo to Custom Fields, Contacts, Organizations, Leads in Insightly with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Insightly, and CRM data flows the other way wherever Klaviyo can store and use it.
