Why teams connect Azure Synapse Analytics and Klaviyo

Get the data locked inside Klaviyo into Azure Synapse Analytics as live tables, and send results back where Klaviyo can use them, without writing a pipeline.

Whatever Klaviyo is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Lists, Segments, Events, Metrics from Klaviyo into tables in Azure Synapse Analytics continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Azure Synapse Analytics can also be written back into fields in Klaviyo where the tool can use them.

Common use cases

  • Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Consolidate SaaS data alongside lake data so analysts join both through one SQL surface.
  • Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.

Cross-tool reporting

Combine Klaviyo's data with data from every other synced system to answer questions no single tool can.

Where Klaviyo accepts updates: operational write-back

Segments, scores, or reference values computed in Azure Synapse Analytics sync back onto records in Klaviyo, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in Azure Synapse Analytics preserves a queryable record even as data ages out of Klaviyo or gets changed inside it.

What you can sync between Azure Synapse Analytics and Klaviyo

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Azure Synapse Analytics objects Klaviyo objects
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
Views Curated projections used when downstream tools should not read base tables directly. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes.
Schemas Namespaces that separate staging, integration, and presentation layers. Lists Static audience memberships sync in from CRMs and forms for targeting.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
