Why teams connect Klaviyo and Zoho CRM

Sync what happens in Klaviyo with the customer records in Zoho CRM, 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 Segments, Events, Metrics, Campaigns in Klaviyo to Lead, Contact, Account, Deal in Zoho CRM with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Zoho CRM, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Push warehouse-computed lead scores and product signals into Zoho CRM fields for rep prioritization.
  • Keep Zoho CRM accounts aligned with an ERP or accounting system on customers and invoices.
