Why teams connect Klaviyo and Veeva CRM

Sync what happens in Klaviyo with the customer records in Veeva 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 Tags, Profiles, Lists, Segments in Klaviyo to Approved Email Activity, Accounts (HCPs and HCOs), Calls, Medical Inquiries in Veeva CRM with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Veeva CRM, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • 01 Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • 02 Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • 03 Mirror medical inquiries into a medical information system for fulfillment and audit.
  • 04 Sync HCP and HCO accounts between Veeva CRM and a customer master or MDM system to keep the customer master aligned.
