Why teams connect Clearbit and Salesforce Marketing Cloud

Flow Clearbit data into Salesforce Marketing Cloud in real time — no exports, no schedulers, no custom scripts.

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

Clearbit owns the customer relationship and the pipeline; Salesforce Marketing Cloud runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Common use cases

  • 01 Append technographic fields to account records in the warehouse for ICP scoring models.
  • 02 Route and score inbound demo requests using Clearbit company size and industry data synced into the CRM.
  • 03 Two-way sync Data Extension rows between Marketing Cloud and a Postgres database or warehouse so audience attributes and opt-out state stay aligned in both systems.
  • 04 Push CRM or warehouse audience segments into Data Extensions via the async rows API (background bulk insert) so marketing sends to freshly built audiences without manual CSV imports.

Common sync patterns

Segments and audiences follow the CRM

Where Salesforce Marketing Cloud builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Clearbit, so who receives a campaign reflects current pipeline reality instead of a stale export.

Where Salesforce Marketing Cloud generates leads: hand-off without re-keying

New leads or responders captured in Salesforce Marketing Cloud flow into Clearbit assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

What you can sync between Clearbit and Salesforce Marketing Cloud

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 Salesforce Marketing Cloud objects How this pairing syncs
Persons Individual profiles looked up by email and used to enrich contacts and leads. Contacts / Subscribers The contact model keyed by Subscriber Key, holding channel addresses and subscription status; managed through the Contacts API (/contacts/v1/contacts) and the SOAP Subscriber object, and referenced by every send and journey. Persons is specific to Clearbit and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Reveal matches IP-to-company resolutions used to identify anonymous website traffic. Journeys (Journey Builder) Multi-step automated flows read and managed via /interaction/v1/interactions; contacts are injected by firing an entry event to /interaction/v1/events with an EventDefinitionKey and contact data. Reveal matches is specific to Clearbit and Journeys (Journey Builder) to Salesforce Marketing Cloud — 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. Content Assets (Content Builder) Emails, templates, images, and reusable content blocks stored in Content Builder and read or written via /asset/v1/content/assets, used to compose the messages a journey or send delivers. Name-to-domain lookups is specific to Clearbit and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Enrichment attributes The firmographic and technographic fields appended to destination records. Automations (Automation Studio) Scheduled or triggered workflows of import, query, extract, and send activities managed via /automation/v1/automations; SQL Query Activities read Data Views and write results into Data Extensions. Enrichment attributes is specific to Clearbit and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Companies Firmographic profiles looked up by domain and merged into account records. Tracking Events Sent, Open, Click, Bounce, Unsubscribe, and NotSent events retrieved through the SOAP tracking objects (SentEvent, OpenEvent, ClickEvent, BounceEvent) or the Automation Studio Data Views (_Sent, _Open, _Click, _Bounce) - the queryable record of engagement per send. Companies is specific to Clearbit and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.

How changes propagate between Clearbit and Salesforce Marketing Cloud

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 Salesforce Marketing Cloud Sub-second propagation

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

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

Salesforce Marketing Cloud Clearbit Sub-second propagation

DetectionSalesforce Marketing Cloud notifies Stacksync of record changes through webhook events. The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback.

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 Salesforce Marketing Cloud records.

Rate-limit considerations

  • Clearbit: Subject to plan-based API rate limits and lookup volumes.
  • Salesforce Marketing Cloud: Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.

Salesforce Marketing Cloud

Integration surface
Two APIs on tenant-specific endpoints: a REST API (JSON over HTTPS) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, plus a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve.
Authentication
OAuth 2.0 via an Installed Package (Client ID + Client Secret). Server-to-server uses the client_credentials grant and web apps use authorization_code, both against {subdomain}.auth.marketingcloudapis.com/v2/token. The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url.
Change detection
The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback URL and subscription are registered and verified. There is no general data-change feed, so Data Extension and Data View syncs poll by date fields.
