Why teams connect BigQuery and Lemlist

Get the data locked inside Lemlist into BigQuery as live tables, and send results back where Lemlist can use them, without writing a pipeline.

Whatever Lemlist is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Activities, Unsubscribes, Webhooks, Team Members from Lemlist into tables in BigQuery continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in BigQuery can also be written back into fields in Lemlist where the tool can use them.

Common use cases

  • Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • Activate modeled BigQuery tables by syncing computed attributes back into sales and marketing tools
  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources

History that outlives the tool

A continuously synced copy in BigQuery preserves a queryable record even as data ages out of Lemlist or gets changed inside it.

Analytics on Lemlist's data

Records and events from Lemlist land in BigQuery as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Lemlist's data with data from every other synced system to answer questions no single tool can.

What you can sync between BigQuery 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.

BigQuery objects Lemlist objects
Tables The syncable unit: only tables can be synced per the Stacksync docs. Webhooks Hook subscriptions define which activity events are pushed to external endpoints.
Partitioned tables Synced like regular tables; partition columns map to target fields. Team Members Sender and seat records map outreach activity to reps in other systems.
Clustered tables Supported; clustering is transparent to the sync. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows.
Datasets Organizational container — you pick which dataset’s tables to sync. Leads Per-campaign prospect records sync in from enrichment sources and back out with status.
Projects Connection scope: the service account grants access per project. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines.
