Why teams connect Eloqua and MotherDuck

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

MotherDuck 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 Views, Database Shares, Attached Local DuckDB Databases, Databases in MotherDuck with Emails, Forms and Form Submits, Contact Lists and Segments, Contacts 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 MotherDuck — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync modeled MotherDuck tables outward to operational tools for activation
  • 02 Share curated, synced datasets with other teams through read-only database shares
  • 03 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.
  • 04 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.

Common sync patterns

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 MotherDuck holds the current state for auditing.

Enrich records with warehouse context

Product-usage counts, plan tier, region, or account owner computed in MotherDuck appear on the matching record in Eloqua, so targeting, routing, and personalization use up-to-date context.

Activate a modeled audience

A segment or score built in MotherDuck — 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.

What you can sync between Eloqua and MotherDuck

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 MotherDuck objects How this pairing syncs
Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Database Shares Read-only copies of a database shared with other users or teams. Emails is specific to Eloqua and Database Shares to MotherDuck — each maps to any object or custom field on the other side.
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. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Forms and Form Submits is specific to Eloqua and Attached Local DuckDB Databases to MotherDuck — 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. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Contact Lists and Segments is specific to Eloqua and Databases to MotherDuck — 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. Schemas Namespaces within a database used to organize synced tables. Contacts is specific to Eloqua and Schemas to MotherDuck — 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. Tables The main landing target for synced records and source for analysis. Accounts is specific to Eloqua and Tables to MotherDuck — 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. Views Modeled projections used as outbound sync sources. Custom Data Objects is specific to Eloqua and Views to MotherDuck — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and MotherDuck

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 MotherDuck 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 MotherDuck as a row-level write, with types converted between the two schemas.

MotherDuck Eloqua Interval-based propagation

DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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.
  • MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
