Why teams connect Klaviyo and Vertica

Get the data locked inside Klaviyo into Vertica 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 Campaigns, Flows, Templates, Catalog Items from Klaviyo into tables in Vertica continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Vertica can also be written back into fields in Klaviyo where the tool can use them.

Common use cases

  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • Consolidate data from multiple operational databases into Vertica schemas for enterprise BI.
  • Sync CRM accounts and opportunities into Vertica to join with large-scale behavioral or telemetry data.

History that outlives the tool

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

Analytics on Klaviyo's data

Records and events from Klaviyo land in Vertica as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

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

What you can sync between Klaviyo and Vertica

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.

Klaviyo objects Vertica objects
Templates Message templates are accessible via API for content management workflows. Views Logical views used to shape reads for downstream consumers.
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Flex Tables Schema-flexible tables for semi-structured JSON data landed before modeling.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. External Tables Data queried in place on files or object storage without loading.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Schemas Namespaces used to organize synced datasets by domain or source.
Lists Static audience memberships sync in from CRMs and forms for targeting. Tables Columnar tables; the primary read and write targets for syncs.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Projections Sorted, encoded physical copies of table data that the optimizer selects at query time; they affect load and query behavior rather than being addressed directly.
