Why teams connect Clearbit and Eloqua

Flow Clearbit data into Eloqua in real time — no exports, no schedulers, no custom scripts.

Clearbit is a read-only source: Stacksync reads its data in real time and delivers it into Eloqua, so Eloqua always reflects the current state of Clearbit — without exports, scripts, or schedulers.

Clearbit owns the customer relationship and the pipeline; Eloqua 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 Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
  • 02 Enrich new CRM leads with person and company attributes as they are created, keyed by email and domain.
  • 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

Where Eloqua captures engagement: activity lands on the record

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

Lead and lifecycle status agree

Status, stage, or score set in one system updates the matching record in the other, so a lead marketing is still nurturing is not worked as sales-ready, and a closed account stops receiving prospecting.

Segments and audiences follow the CRM

Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Clearbit, so who receives a campaign reflects current pipeline reality instead of a stale export.

What you can sync between Clearbit and Eloqua

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.

Clearbit objects Eloqua objects How this pairing syncs
Companies Firmographic profiles looked up by domain and merged into account records. 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. Companies is specific to Clearbit and Accounts to Eloqua — each maps to any object or custom field on the other side.
Persons Individual profiles looked up by email and used to enrich contacts and leads. 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. Persons is specific to Clearbit and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side.
Reveal matches IP-to-company resolutions used to identify anonymous website traffic. 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. Reveal matches is specific to Clearbit and Activities to Eloqua — each maps to any object or custom field on the other side.
Name-to-domain lookups Company name resolution used to normalize account records before enrichment. Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Name-to-domain lookups is specific to Clearbit and Campaigns to Eloqua — each maps to any object or custom field on the other side.
Enrichment attributes The firmographic and technographic fields appended to destination records. Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Enrichment attributes is specific to Clearbit and Emails to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between Clearbit and Eloqua

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.

Clearbit Eloqua Sub-second propagation

DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.

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

Eloqua Clearbit 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.

DeliveryClearbit does not accept inbound record writes, so this direction carries requests rather than records: Clearbit's output flows back as field updates on the originating Eloqua records.

Rate-limit considerations

  • Clearbit: Subject to plan-based API rate limits and lookup volumes.
  • 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.
