Why teams connect Customer.io and Yellowbrick

Get the data locked inside Customer.io into Yellowbrick 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 People, Objects, Events, Segments from Customer.io into tables in Yellowbrick continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Yellowbrick can also be written back into fields in Customer.io where the tool can use them.

Common use cases

  • Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • Push warehouse-computed aggregates or segments back into operational tools such as a CRM.
  • Sync CRM and marketing data into Yellowbrick tables so it can be joined with large fact tables for enterprise BI.

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 Yellowbrick sync back onto records in Customer.io, putting analysis where the work happens.

History that outlives the tool

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

What you can sync between Customer.io and Yellowbrick

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.

Broadcasts One-off sends to segments or audiences, triggerable via API. Tables Columnar MPP tables; the primary targets for warehouse syncs.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Views Logical views used to shape reads for BI and downstream syncs.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Users and Roles Access-control objects that govern what a sync service account can read and write.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Databases Top-level containers for schemas and tables.

How the Customer.io and Yellowbrick connectors work

Customer.io

Integration surface
REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
Authentication
Basic auth with site ID and API key for the Track API; bearer token for the App API
Change detection
Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
Capabilities
read · write · webhooks
Rate limits
Subject to per-API rate limits documented by Customer.io

Yellowbrick

Integration surface
SQL wire protocol (PostgreSQL-compatible) with JDBC/ODBC drivers; bulk loading via the ybload utility
Authentication
Database credentials, with LDAP and Kerberos options in enterprise deployments
Change detection
Polling on timestamp columns; no exposed transaction-log CDC
Capabilities
read · write
Rate limits
No API rate limits; throughput depends on cluster sizing, and bulk loads should use ybload rather than row-by-row inserts.
