Why teams connect Customer.io and ZoomInfo
Flow ZoomInfo data into Customer.io in real time — no exports, no schedulers, no custom scripts.
ZoomInfo is a read-only source: Stacksync reads its data in real time and delivers it into Customer.io, so Customer.io always reflects the current state of ZoomInfo — without exports, scripts, or schedulers.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Customer.io holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
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.
- Feed technographic data into territory plans or scoring models in a warehouse.
- Align CRM account hierarchies with ZoomInfo's corporate hierarchy data.
Where Customer.io can store CRM context: fields kept current
Owner, lifecycle stage, or account details from ZoomInfo sync into Customer.io, so people working there have the context without switching tools.
Where Customer.io handles support or shared inboxes
Tickets and conversations attach to the right contact and account in ZoomInfo, so sales sees open issues before the next call.
Where Customer.io runs outreach
Prospects, sends, and replies sync into ZoomInfo, keeping lead status current without manual imports.

FAQ
Customer.io and ZoomInfo integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Customer.io and ZoomInfo — ZoomInfo is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Customer.io: The Track API is ingestion-oriented: integrations identify people and send events, and Customer.io matches records on identifiers such as id or email. ZoomInfo: The API is built around search and enrich operations: integrations submit known attributes such as domain, email, or name and receive matched, filled-out profiles. Stacksync's field mapping accounts for these differences between Customer.io and ZoomInfo 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 ZoomInfo 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 ZoomInfo connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Customer.io–ZoomInfo integration in-house.
