Why teams connect Salesforce Marketing Cloud and ZoomInfo

Flow ZoomInfo data into Salesforce Marketing Cloud 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 Salesforce Marketing Cloud, so Salesforce Marketing Cloud always reflects the current state of ZoomInfo — without exports, scripts, or schedulers.

ZoomInfo 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 Feed technographic data into territory plans or scoring models in a warehouse.
  • 02 Align CRM account hierarchies with ZoomInfo's corporate hierarchy data.
  • 03 Land tracking events - Sent, Open, Click, Bounce, Unsubscribe - from the SOAP tracking objects or Automation Studio Data Views into a warehouse table for per-send deliverability reporting.
  • 04 Sync Contacts and Subscriber Key subscription status between Marketing Cloud and a CRM so suppression and opt-in state stay current before the next send.

Common sync patterns

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

New leads or responders captured in Salesforce Marketing Cloud flow into ZoomInfo 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.

Where Salesforce Marketing Cloud captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Salesforce Marketing Cloud post back to the contact or account in ZoomInfo, so reps see interest before they reach out.

What you can sync between Salesforce Marketing Cloud 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.

Salesforce Marketing Cloud objects ZoomInfo objects How this pairing syncs
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. Scoops Event-driven signals such as leadership changes, funding rounds, and new projects. Contacts / Subscribers is specific to Salesforce Marketing Cloud and Scoops to ZoomInfo — each maps to any object or custom field on the other side.
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. Technographics Technology install data per company, used for segmentation and territory planning. Journeys (Journey Builder) is specific to Salesforce Marketing Cloud and Technographics to ZoomInfo — each maps to any object or custom field on the other side.
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. Company Hierarchies Parent and subsidiary linkage used to align CRM account hierarchies. Content Assets (Content Builder) is specific to Salesforce Marketing Cloud and Company Hierarchies to ZoomInfo — each maps to any object or custom field on the other side.
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. Company Profiles Firmographic records covering industry, size, revenue, and location, matched against CRM accounts. Automations (Automation Studio) is specific to Salesforce Marketing Cloud and Company Profiles to ZoomInfo — each maps to any object or custom field on the other side.
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. Contact Profiles Person records with title, email, phone, and company linkage, used to enrich leads and contacts. Tracking Events is specific to Salesforce Marketing Cloud and Contact Profiles to ZoomInfo — each maps to any object or custom field on the other side.
Transactional Sends Triggered and transactional Email/SMS delivered through the Messaging API (/messaging/v1/email/messages/{key}); the Event Notification Service reports each message's disposition (delivered, bounced, opened, clicked). Intent Signals Company-level topic scores indicating in-market buying behavior. Transactional Sends is specific to Salesforce Marketing Cloud and Intent Signals to ZoomInfo — each maps to any object or custom field on the other side.

How changes propagate between Salesforce Marketing Cloud 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.

Salesforce Marketing Cloud ZoomInfo 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.

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 Salesforce Marketing Cloud records.

ZoomInfo Salesforce Marketing Cloud 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 Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • 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.
  • ZoomInfo: Usage is metered by credits and contract-based limits rather than a single public rate limit.

How the Salesforce Marketing Cloud and ZoomInfo connectors work

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.
