Why teams connect Clearbit and Lemlist

Flow Clearbit data into Lemlist 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 Lemlist, so Lemlist always reflects the current state of Clearbit — without exports, scripts, or schedulers.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Lemlist holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Common use cases

  • Stop or pause sequences automatically when a reply converts to a deal in the CRM
  • Mirror campaign performance data into BI tools for outbound reporting across senders
  • Enrich new CRM leads with person and company attributes as they are created, keyed by email and domain.
  • Append technographic fields to account records in the warehouse for ICP scoring models.

Where Lemlist can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Clearbit sync into Lemlist, so people working there have the context without switching tools.

Where Lemlist runs outreach

Prospects, sends, and replies sync into Clearbit, keeping lead status current without manual imports.

Where Lemlist supplies contact or company data

Enriched fields land directly on records in Clearbit, and refreshes keep them from going stale.

What you can sync between Clearbit and Lemlist

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 Lemlist objects
Enrichment attributes The firmographic and technographic fields appended to destination records. Team Members Sender and seat records map outreach activity to reps in other systems.
Companies Firmographic profiles looked up by domain and merged into account records. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows.
Persons Individual profiles looked up by email and used to enrich contacts and leads. Leads Per-campaign prospect records sync in from enrichment sources and back out with status.
Reveal matches IP-to-company resolutions used to identify anonymous website traffic. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines.
Name-to-domain lookups Company name resolution used to normalize account records before enrichment. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance.
