Why teams connect Lemlist and SingleStore

Mirror Lemlist's data into SingleStore so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Lemlist through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in SingleStore.

Stacksync mirrors Unsubscribes, Webhooks, Team Members, Campaigns from Lemlist into Tables (rowstore and columnstore), Views, Reference Tables, Pipelines in SingleStore and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Lemlist, so the tool and the database never disagree.

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
  • Sync results of real-time analytical queries back into business tools where teams act on them.
  • Consolidate data from transactional databases and SaaS apps into one store that handles both lookups and scans.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Lemlist with a query

Records from Lemlist are ordinary rows in SingleStore; join them, index them, and use them in application logic without touching the vendor API.

Automate Lemlist from your codebase

Write to the synced tables in SingleStore and Stacksync propagates the change into Lemlist, replacing custom integration code.

What you can sync between Lemlist and SingleStore

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 SingleStore objects
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Views Read-only projections used as curated sync sources.
Team Members Sender and seat records map outreach activity to reps in other systems. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Stored Procedures Existing logic sometimes invoked on write paths.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys.
