Why teams connect Clearbit and Easypost

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

Clearbit 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 Clearbit — without exports, scripts, or schedulers.

Clearbit 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 new CRM leads with person and company attributes as they are created, keyed by email and domain.
  • 02 Append technographic fields to account records in the warehouse for ICP scoring models.
  • 03 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 04 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

Common sync patterns

Where both keep product records: catalog and CRM products aligned

Where Clearbit tracks products or line items and Easypost holds the catalog, shared items are matched on SKU so quotes, deals, and orders reference the same products.

One customer identity across sales and store

A person who exists as a contact in Clearbit and a buyer in Easypost is kept as a single, deduplicated record, so both teams work from the same customer instead of two partial copies.

Where Easypost records orders: purchase history on the account

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

What you can sync between Clearbit and Easypost

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.

Clearbit objects Easypost objects How this pairing syncs
Reveal matches IP-to-company resolutions used to identify anonymous website traffic. 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. Reveal matches is specific to Clearbit and Batch to Easypost — each maps to any object or custom field on the other side.
Name-to-domain lookups Company name resolution used to normalize account records before enrichment. CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Name-to-domain lookups is specific to Clearbit and CarrierAccount to Easypost — each maps to any object or custom field on the other side.
Enrichment attributes The firmographic and technographic fields appended to destination records. 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. Enrichment attributes is specific to Clearbit and Webhook to Easypost — each maps to any object or custom field on the other side.
Companies Firmographic profiles looked up by domain and merged into account records. 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. Companies is specific to Clearbit and Shipment to Easypost — each maps to any object or custom field on the other side.
Persons Individual profiles looked up by email and used to enrich contacts and leads. 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. Persons is specific to Clearbit and Address to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Clearbit and Easypost

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.

Clearbit Easypost Sub-second propagation

DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.

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

Easypost Clearbit Sub-second propagation

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

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

Rate-limit considerations

  • Clearbit: Subject to plan-based API rate limits and lookup volumes.
  • 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.
