Why teams connect Eloqua and Snowflake

Put modeled data to work and measure what it drives: Snowflake and Eloqua keep contacts, audiences, and campaign results in step in real time, in both directions.

Snowflake is where your team models customers, product usage, and revenue into trusted tables; Eloqua runs the campaigns, audiences, and messages that reach those people. The two overlap wherever the same person, account, or segment matters to both, and when the bridge between them is a nightly export or a hand-built list, marketing targets stale data while analytics never sees what the campaign returned.

Stacksync syncs Schemas, Tables, Views, Materialized Views in Snowflake with Contacts, Accounts, Custom Data Objects, Activities in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — a computed score or segment can flow out to Eloqua while sends, opens, and conversions flow back to Snowflake — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL
  • 02 Activate modeled Snowflake tables by syncing scores and attributes back into CRM fields sales can act on
  • 03 Two-way sync Contacts between Eloqua and a Postgres or warehouse table, matched on email, so ops teams query and update marketing profiles in SQL while marketers keep working in Eloqua.
  • 04 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.

Common sync patterns

Activate a modeled audience

A segment or score built in Snowflake — high-intent accounts, churn risk, a lifetime-value tier — lands as an audience or contact field in Eloqua, so campaigns target the people your data actually points to instead of a static export.

Keep the contact and audience list current

New and updated contacts, leads, or audience members flow between Snowflake and Eloqua, so the marketing audience reflects the people in your warehouse and corrections propagate instead of the two sides drifting apart.

Suppression and consent stay aligned

Unsubscribes, bounces, and consent or opt-out flags held in either system propagate to the other, so no one is messaged after opting out and Snowflake holds the current state for auditing.

What you can sync between Eloqua and Snowflake

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.

Eloqua objects Snowflake objects How this pairing syncs
Forms and Form Submits Form definitions and their submission data, accessed through the Application REST API; submissions read out into a warehouse for lead capture and analysis. Tasks Scheduled SQL used to transform synced data after it lands. Forms and Form Submits is specific to Eloqua and Tasks to Snowflake — each maps to any object or custom field on the other side.
Contact Lists and Segments Shared lists (static) and segments (dynamic audiences); Contacts are added to or removed from shared lists based on lifecycle stage computed downstream. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns. Contact Lists and Segments is specific to Eloqua and VARIANT Columns to Snowflake — each maps to any object or custom field on the other side.
Contacts Core person records, keyed on email address as the unique identifier; imported/exported via the Bulk API and upserted on email, synced two-way with CRM, warehouse, and app databases. Virtual Warehouses The compute a sync's queries run on, sized independently of storage. Contacts is specific to Eloqua and Virtual Warehouses to Snowflake — each maps to any object or custom field on the other side.
Accounts Company records linked to Contacts via the account-linkage field; moved through the Bulk API and typically mastered in a CRM or ERP and written into Eloqua. Databases Top-level containers that scope which data a sync can touch. Accounts is specific to Eloqua and Databases to Snowflake — each maps to any object or custom field on the other side.
Custom Data Objects Auxiliary data tables (CDOs) linked to Contacts for records like event registrations or purchases; synced via the Bulk API so nurture campaigns can branch on them. Schemas Namespaces within a database used to organize synced tables. Custom Data Objects is specific to Eloqua and Schemas to Snowflake — each maps to any object or custom field on the other side.
Activities Engagement events (email opens, clicks, form submits, bounces, page views, subscribes/unsubscribes) exported through the Bulk API activities export; read-only feed for scoring and attribution. Tables The main landing and activation target for synced records. Activities is specific to Eloqua and Tables to Snowflake — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Snowflake

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.

Eloqua Snowflake Interval-based propagation

DetectionStacksync polls Eloqua for changes on an incremental schedule, reading only records changed since the previous pass. Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax.

DeliveryEach detected change is applied to Snowflake as a row-level write, with types converted between the two schemas.

Snowflake Eloqua Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

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

Rate-limit considerations

  • Eloqua: Per-instance soft limits by sync type (Export 2,000/hr, Import 2,000/hr, Sync Action 4,000/hr); 32 MB cap per POST to a staging area and 50,000 records per retrieve batch.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
