Why teams connect Customer.io and Tinybird

Get the data locked inside Customer.io into Tinybird as live tables, and send results back where Customer.io can use them, without writing a pipeline.

Whatever Customer.io 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 Deliveries / Messages, Newsletters, People, Objects from Customer.io into tables in Tinybird continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Tinybird can also be written back into fields in Customer.io where the tool can use them.

Common use cases

  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Compute aggregates in Tinybird and write the results back to CRM fields for scoring and routing.
  • Stream CRM activity such as deals and tickets into Tinybird Data Sources to power customer-facing dashboards.

Analytics on Customer.io's data

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

Cross-tool reporting

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

Where Customer.io accepts updates: operational write-back

Segments, scores, or reference values computed in Tinybird sync back onto records in Customer.io, putting analysis where the work happens.

What you can sync between Customer.io and Tinybird

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.

Customer.io objects Tinybird objects
Events Behavioral events sent via the Track API that trigger campaigns. Tokens Scoped credentials that control read and append rights per resource.
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Data Sources ClickHouse-backed tables that receive ingested rows; the write target for syncs into Tinybird.
Campaigns Automated workflows whose membership and metrics can be read via the App API. Pipes Chained SQL nodes that transform Data Sources into query-ready results.
Broadcasts One-off sends to segments or audiences, triggerable via API. API Endpoints Published Pipe outputs exposed as parameterized HTTP queries; the main read surface.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Materialized Views Pipes materialized into new Data Sources for pre-aggregation at ingest time.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Workspaces Project boundary that scopes Data Sources, Pipes, and tokens for a sync.
