Why teams connect Customer.io and Dun And Bradstreet

Flow Dun And Bradstreet data into Customer.io in real time — no exports, no schedulers, no custom scripts.

Dun And Bradstreet 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 Dun And Bradstreet — 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

  • 01 Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • 02 Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
  • 03 Poll D&B Monitoring notifications for a registered portfolio of key accounts and suppliers and update the CRM or warehouse record whenever a firmographic or risk score changes.
  • 04 Pull D&B risk and credit signals (PAYDEX, Failure Score, D&B Rating) into a warehouse for credit-risk, vendor-risk, and third-party-risk analytics.

How changes propagate between Customer.io and Dun And Bradstreet

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Customer.io Dun And Bradstreet Sub-second propagation

DetectionCustomer.io notifies Stacksync of record changes through webhook events. Reporting webhooks push message and delivery events.

DeliveryDun And Bradstreet does not accept inbound record writes, so this direction carries requests rather than records: Dun And Bradstreet's output flows back as field updates on the originating Customer.io records.

Dun And Bradstreet Customer.io Interval-based propagation

DetectionStacksync polls Dun And Bradstreet for changes on an incremental schedule, reading only records changed since the previous pass. Polling via D&B Monitoring - register a portfolio of DUNS and pull change notices from the notifications endpoint (retained ~60 days).

DeliveryEach detected change is written to Customer.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Customer.io: Subject to per-API rate limits documented by Customer.io.
  • Dun And Bradstreet: Per-contract transactions-per-second cap plus weekly/monthly/yearly quotas; exceeding TPS returns HTTP 429 with error 0045/0046 (0047 on spike arrest). Quotas reset on UTC boundaries.
