Why teams connect Klaviyo and Vitally

Sync what happens in Klaviyo with the customer records in Vitally, 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 Metrics, Campaigns, Flows, Templates in Klaviyo to Organization, Task, Note, Conversation in Vitally with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Vitally, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Mirror product-usage traits and NPS responses into a warehouse for retention and expansion reporting.
  • 04 Push billing and subscription changes from an ERP or billing system into Vitally to keep success playbooks accurate.
