Why teams connect Klaviyo and SingleStore

Mirror Klaviyo's data into SingleStore so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Klaviyo through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in SingleStore.

Stacksync mirrors Metrics, Campaigns, Flows, Templates from Klaviyo into Pipelines, Stored Procedures, Indexes and Shard Keys, Databases in SingleStore and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Klaviyo, so the tool and the database never disagree.

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
  • Sync results of real-time analytical queries back into business tools where teams act on them.
  • Consolidate data from transactional databases and SaaS apps into one store that handles both lookups and scans.

React to changes as they happen

Updates in Klaviyo arrive as row changes in SingleStore, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in SingleStore; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Klaviyo and SingleStore

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 SingleStore objects
Templates Message templates are accessible via API for content management workflows. Databases The connection target containing the tables a sync addresses.
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Views Read-only projections used as curated sync sources.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Lists Static audience memberships sync in from CRMs and forms for targeting. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Stored Procedures Existing logic sometimes invoked on write paths.
