Why teams connect Lemlist and Supabase

Mirror Lemlist's data into Supabase 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 Supabase.

Stacksync mirrors Activities, Unsubscribes, Webhooks, Team Members from Lemlist into Tables, Views, Schemas, auth.users in Supabase 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
  • Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
  • Sync application tables in Supabase with the CRM two-way so new signups appear as contacts and sales edits flow back to the app

Read Lemlist with a query

Records from Lemlist are ordinary rows in Supabase; 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 Supabase and Stacksync propagates the change into Lemlist, replacing custom integration code.

React to changes as they happen

Updates in Lemlist arrive as row changes in Supabase, so triggers, jobs, and services can respond in near real time.

What you can sync between Lemlist and Supabase

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 Supabase objects
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Database Functions Postgres functions that can transform or validate synced rows.
Team Members Sender and seat records map outreach activity to reps in other systems. Storage Object Metadata File metadata rows that can be joined to synced application data.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Tables Standard Postgres tables; the primary two-way sync target.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Views Read-side projections exposed to outbound syncs.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Schemas Namespaces (public and custom) that scope sync access.
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. auth.users Managed authentication users, often mirrored into CRM or support systems.
