Why teams connect Klaviyo and Kommo

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

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. 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 Leads, Contacts, Companies, Pipelines & Statuses in Kommo with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Kommo, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Route leads that originate in WhatsApp or Instagram conversations into other systems of record
  • Replicate Kommo leads and contacts into a database or warehouse for reporting beyond built-in dashboards
