Why teams connect BigQuery and Klaviyo

Get the data locked inside Klaviyo into BigQuery 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 Tags, Profiles, Lists, Segments from Klaviyo into tables in BigQuery continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in BigQuery can also be written back into fields in Klaviyo where the tool can use them.

Common use cases

  • Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule

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 BigQuery sync back onto records in Klaviyo, putting analysis where the work happens.

History that outlives the tool

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

What you can sync between BigQuery 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.

BigQuery objects Klaviyo objects
Clustered tables Supported; clustering is transparent to the sync. Lists Static audience memberships sync in from CRMs and forms for targeting.
Datasets Organizational container — you pick which dataset’s tables to sync. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Projects Connection scope: the service account grants access per project. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
Partitioned tables Synced like regular tables; partition columns map to target fields. Campaigns Email and SMS sends expose performance data for warehouse-based reporting.
