Why teams connect Outreach and Salesforce Marketing Cloud

Keep the people you sell to and the people you market to in one shared view: Outreach and Salesforce Marketing Cloud sync contacts, accounts, and engagement in real time, in both directions.

Outreach 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.

Stacksync syncs Calls, Tasks, Opportunities, Users in Outreach with Automations (Automation Studio), Tracking Events, Transactional Sends, Data Extensions in Salesforce Marketing Cloud field by field, in real time, and in both directions. You decide which system owns which fields — Outreach can own account and opportunity status while Salesforce Marketing Cloud owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Suppress prospects across systems when a contact unsubscribes or a customer churns.
  • 02 Enroll leads in sequences automatically by writing sequence-state records when a lead crosses a scoring threshold in the warehouse.
  • 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

Segments and audiences follow the CRM

Where Salesforce Marketing Cloud builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Outreach, 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 Outreach 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 Outreach 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.

Outreach objects Salesforce Marketing Cloud objects How this pairing syncs
Mailboxes Connected sending accounts referenced when attributing outbound activity Data Extensions Custom relational tables that store subscriber, audience, and arbitrary business data; rows are read via GET /data/v1/customobjectdata or SOAP Retrieve and upserted via the synchronous rowset PUT or the async /data/v1/async/dataextensions rows endpoint. This is the primary two-way surface. Mailboxes is specific to Outreach and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Prospects The people being engaged; the main record kept in sync with the CRM 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. Prospects is specific to Outreach and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Accounts Companies grouping prospects, aligned with CRM account ownership 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. Accounts is specific to Outreach and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Sequences Multi-step cadences; synced as reference data for enrollment automation 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. Sequences is specific to Outreach and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Sequence states Per-prospect enrollments; writing one adds a prospect to a cadence 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. Sequence states is specific to Outreach and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Mailings Sent emails with engagement data, pulled for activity analytics 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. Mailings is specific to Outreach and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.

How changes propagate between Outreach 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.

Outreach Salesforce Marketing Cloud Sub-second propagation

DetectionOutreach notifies Stacksync of record changes through webhook events. Webhook subscriptions on resource create, update, and destroy events, plus polling.

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

Salesforce Marketing Cloud Outreach 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.

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

Rate-limit considerations

  • Outreach: Subject to per-user hourly rate limits.
  • 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.
