Why teams connect Klaviyo and Microsoft Dynamics 365 Sales
Sync what happens in Klaviyo with the customer records in Microsoft Dynamics 365 Sales, 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 Orders, Invoices, Activities, Custom Tables in Microsoft Dynamics 365 Sales with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Microsoft Dynamics 365 Sales, 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
- Feed BI models with continuously updated CRM data instead of scheduled exports.
- Bi-directional sync of accounts, contacts, and opportunities with a SQL database so teams query CRM data without OData or FetchXML.

Enriched fields land directly on records in Microsoft Dynamics 365 Sales, and refreshes keep them from going stale.
Where Klaviyo processes payments

Where Klaviyo can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Microsoft Dynamics 365 Sales sync into Klaviyo, so people working there have the context without switching tools.
