Why teams connect Lemlist and Snowflake

Get the data locked inside Lemlist into Snowflake 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 Snowflake continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Snowflake can also be written back into fields in Lemlist where the tool can use them.

Common use cases

  • Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • Stop or pause sequences automatically when a reply converts to a deal in the CRM
  • Push product usage aggregates from Snowflake into sales and success tools for account prioritization
  • Feed finance reconciliation models from ERP data landed in Snowflake on a continuous basis

History that outlives the tool

A continuously synced copy in Snowflake 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 Snowflake 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 Lemlist 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.

Lemlist objects Snowflake objects
Team Members Sender and seat records map outreach activity to reps in other systems. Databases Top-level containers that scope which data a sync can touch.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Schemas Namespaces within a database used to organize synced tables.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Tables The main landing and activation target for synced records.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Views Modeled projections used as the source side of outbound syncs.
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Materialized Views Precomputed results synced outward for low-latency reads.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Streams Row-level change records on a table, consumed to process deltas instead of full scans.
