Why teams connect Customer.io and Vertica
Get the data locked inside Customer.io into Vertica 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 Newsletters, People, Objects, Events from Customer.io 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 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.
- Land ERP transactions in Vertica for finance analytics without maintaining hand-built ETL jobs.
- Push segments or aggregates computed in Vertica back into operational tools such as a CRM.
History that outlives the tool
A continuously synced copy in Vertica preserves a queryable record even as data ages out of Customer.io or gets changed inside it.
Analytics on Customer.io's data
Records and events from Customer.io land in Vertica 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.
What you can sync between Customer.io 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.
| Customer.io objects | Vertica objects | |
|---|---|---|
| Broadcasts One-off sends to segments or audiences, triggerable via API. | External Tables Data queried in place on files or object storage without loading. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Schemas Namespaces used to organize synced datasets by domain or source. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Tables Columnar tables; the primary read and write targets for syncs. | |
| People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | 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. | |
| Objects Non-person entities such as accounts or companies, related to people for account-level messaging. | Views Logical views used to shape reads for downstream consumers. | |
| Events Behavioral events sent via the Track API that trigger campaigns. | Flex Tables Schema-flexible tables for semi-structured JSON data landed before modeling. |

How the Customer.io and Vertica 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
Vertica
- Integration surface
- SQL over JDBC, ODBC, and ADO.NET drivers
- Authentication
- Database credentials, with LDAP, Kerberos, and OAuth options in enterprise deployments
- Change detection
- No exposed transaction-log CDC; polling on timestamp or epoch columns
- Capabilities
- read · write
- Rate limits
- No API rate limits; throughput is bounded by cluster resources, and bulk COPY is preferred over row-by-row writes.

FAQ
Customer.io and Vertica integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Vertica: authenticate both systems, choose the objects to sync (such as Customer.io's Broadcasts and Deliveries / Messages), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Customer.io: Reporting webhooks emit granular message lifecycle events, which is the practical way to get engagement data out at scale. Vertica: Vertica organizes storage as projections rather than indexes: each table has one or more sorted, compressed physical copies the optimizer chooses among. Stacksync's field mapping accounts for these differences between Customer.io and Vertica without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Customer.io and Vertica records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Customer.io and Vertica connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Customer.io–Vertica integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Customer.io and Vertica. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Customer.io: Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection. On Vertica: No exposed transaction-log CDC; polling on timestamp or epoch columns. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
