Why teams connect Easypost and ZoomInfo

Keep the customers and orders that ZoomInfo and Easypost share aligned in real time, so sales works from live purchase history and the store works from current account details.

ZoomInfo is a read-only source: Stacksync reads its data in real time and delivers it into Easypost, so Easypost always reflects the current state of ZoomInfo — without exports, scripts, or schedulers.

ZoomInfo holds the customer relationship: the contacts, accounts, and deals a go-to-market team works. Easypost runs the buying side: who placed which order, what they bought, and where it ships. The two describe the same people and companies, and when they are connected only by exports, sales answers questions without recent orders in front of them while the store works from account details that changed weeks ago.

The shared entity is the customer, matched on email or an external ID, so both systems agree on who the buyer is and the order history sits next to the relationship instead of in a separate tab.

Common use cases

  • 01 Enrich CRM accounts and contacts on a schedule so firmographics, titles, and phone numbers stay current.
  • 02 Sync intent signals into the CRM or warehouse to trigger outbound plays on in-market accounts.
  • 03 When an order is ready to ship in an OMS, ERP, or database, create an EasyPost Shipment, buy the lowest qualifying Rate, and write the label URL and tracking code back onto the order.
  • 04 Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.

Common sync patterns

Where Easypost records orders: purchase history on the account

Orders and their status from Easypost appear on the matching contact or account in ZoomInfo, so reps see what a customer has bought and what is in flight before the next conversation.

New buyers become CRM records

A customer created in Easypost creates or updates the matching contact or account in ZoomInfo, so first-time and repeat buyers land in the relationship system without a manual import.

Contact and address details stay consistent

An email, phone, or shipping and billing address corrected in either system updates the other, so the next order and the next outreach both use current information.

What you can sync between Easypost and ZoomInfo

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.

Easypost objects ZoomInfo objects How this pairing syncs
Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. Company Profiles Firmographic records covering industry, size, revenue, and location, matched against CRM accounts. Tracker is specific to Easypost and Company Profiles to ZoomInfo — each maps to any object or custom field on the other side.
Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Contact Profiles Person records with title, email, phone, and company linkage, used to enrich leads and contacts. Batch is specific to Easypost and Contact Profiles to ZoomInfo — each maps to any object or custom field on the other side.
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Intent Signals Company-level topic scores indicating in-market buying behavior. CarrierAccount is specific to Easypost and Intent Signals to ZoomInfo — each maps to any object or custom field on the other side.
Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Scoops Event-driven signals such as leadership changes, funding rounds, and new projects. Webhook is specific to Easypost and Scoops to ZoomInfo — each maps to any object or custom field on the other side.
Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Technographics Technology install data per company, used for segmentation and territory planning. Shipment is specific to Easypost and Technographics to ZoomInfo — each maps to any object or custom field on the other side.
Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. Company Hierarchies Parent and subsidiary linkage used to align CRM account hierarchies. Address is specific to Easypost and Company Hierarchies to ZoomInfo — each maps to any object or custom field on the other side.

How changes propagate between Easypost and ZoomInfo

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.

Easypost ZoomInfo Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

DeliveryZoomInfo does not accept inbound record writes, so this direction carries requests rather than records: ZoomInfo's output flows back as field updates on the originating Easypost records.

ZoomInfo Easypost Interval-based propagation

DetectionStacksync polls ZoomInfo for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled re-enrichment and polling.

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

Rate-limit considerations

  • Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
  • ZoomInfo: Usage is metered by credits and contract-based limits rather than a single public rate limit.
