Why teams connect Customer.io and Exasol

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

Common use cases

  • Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • Sync computed metrics or customer segments from Exasol back into a CRM for sales and marketing use (reverse ETL).
  • Consolidate data from multiple operational databases into Exasol as the central analytics layer.

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

History that outlives the tool

A continuously synced copy in Exasol 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 Exasol

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 Exasol objects
Campaigns Automated workflows whose membership and metrics can be read via the App API. Schemas Namespaces that group the tables a sync reads from or writes into.
Broadcasts One-off sends to segments or audiences, triggerable via API. Tables Primary sync target; columnar relational tables written with standard SQL.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Views Read-only query surfaces often used as curated sources for reverse ETL.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Virtual schemas Federated views over external sources; useful for deciding what needs physical replication.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. UDF scripts In-database functions that can transform synced data after load.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Users and roles Grant read/write access for the dedicated integration account.

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

Exasol

Integration surface
SQL over JDBC/ODBC drivers and a WebSocket-based client protocol
Authentication
Database credentials (username and password)
Change detection
Polling with timestamp or key columns; Exasol does not expose a transaction-log change feed to clients
Capabilities
