Why teams connect Lemlist and Materialize

Get the data locked inside Lemlist into Materialize 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 Unsubscribes, Webhooks, Team Members, Campaigns from Lemlist into tables in Materialize continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Materialize 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
  • Maintain real-time inventory, usage, or account-health counters consumed by customer-facing applications.
  • Bridge streaming sources and non-streaming destinations by materializing joins across both.

Where Lemlist accepts updates: operational write-back

Segments, scores, or reference values computed in Materialize sync back onto records in Lemlist, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in Materialize 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 Materialize as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between Lemlist and Materialize

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 Materialize objects
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets.
Team Members Sender and seat records map outreach activity to reps in other systems. Sinks Outbound connections that emit view changes to Kafka topics.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Indexes In-memory arrangements that make view reads fast for serving workloads.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Connections & Secrets Stored credentials and endpoints used by sources and sinks.
