Two-way sync
Changes in Google Cloud Spanner or Salesforce Marketing Cloud instantly reflect in both systems. No stale data, no manual imports.
Keep Google Cloud Spanner and Salesforce Marketing Cloud in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Salesforce Marketing Cloud holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in Google Cloud Spanner, hard to get into campaigns without manual exports.
Stacksync mirrors Transactional Sends, Data Extensions, Contacts / Subscribers, Journeys (Journey Builder) from Salesforce Marketing Cloud into Databases, Tables, Rows, Interleaved tables in Google Cloud Spanner field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in Google Cloud Spanner, from usage, orders, or account status, sync back into Salesforce Marketing Cloud to drive campaigns and ads, with Salesforce Marketing Cloud kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.
Contacts, leads, audiences, and campaign metrics from Salesforce Marketing Cloud live in Google Cloud Spanner as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.
Segments computed in Google Cloud Spanner from product usage, orders, or account status sync into Salesforce Marketing Cloud as lists or audiences, so campaigns and ads target the people your data says they should.
Opens, clicks, sends, RSVPs, or ad activity from Salesforce Marketing Cloud land in Google Cloud Spanner beside the matching customer record, ready for reporting and revenue attribution.
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.
| Google Cloud Spanner objects | Salesforce Marketing Cloud objects | How this pairing syncs | |
|---|---|---|---|
| Tables Relational tables mapped one-to-one to sync targets. | 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. | Tables is specific to Google Cloud Spanner and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Rows The unit of read and write in each sync cycle, keyed by primary key. | 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. | Rows is specific to Google Cloud Spanner and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Interleaved tables Child rows physically co-located with parents; synced as related records. | 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). | Interleaved tables is specific to Google Cloud Spanner and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Secondary indexes Used to make incremental read queries efficient on non-key columns. | 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. | Secondary indexes is specific to Google Cloud Spanner and Data Extensions to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Change streams Capture inserts, updates, and deletes for log-style change data capture. | 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. | Change streams is specific to Google Cloud Spanner and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. | |
| Views Read-only projections useful for shaping data before it leaves Spanner. | 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. | Views is specific to Google Cloud Spanner and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side. |
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.
DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.
DeliveryEach detected change is written to Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.
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 applied to Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Yes. Stacksync provides a managed, real-time two-way integration between Google Cloud Spanner and Salesforce Marketing Cloud: authenticate both systems, choose the objects to sync (such as Google Cloud Spanner's Tables and Rows), map fields visually, and changes propagate both ways in milliseconds — no code required.
Google Cloud Spanner: Change streams record row-level inserts, updates, and deletes and can be consumed through the API for CDC pipelines. Salesforce Marketing Cloud: Marketing Cloud uses tenant-specific endpoints; OAuth v2 tokens come from an Installed Package's Client ID/Secret at {subdomain}.auth.marketingcloudapis.com/v2/token and expire after 20 minutes. Stacksync's field mapping accounts for these differences between Google Cloud Spanner and Salesforce Marketing Cloud without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Google Cloud Spanner and Salesforce Marketing Cloud records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Google Cloud Spanner and Salesforce Marketing Cloud connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Google Cloud Spanner–Salesforce Marketing Cloud integration in-house.
Yes — Stacksync ships production-grade connectors for both Google Cloud Spanner and Salesforce Marketing Cloud. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Google Cloud Spanner: Change streams (log-style CDC), or timestamp-based polling queries. On Salesforce Marketing Cloud: 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. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
