Why teams connect Lemlist and Scaleway Postgres
Mirror Lemlist's data into Scaleway Postgres 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 Scaleway Postgres.
Stacksync mirrors Team Members, Campaigns, Leads, Activities from Lemlist into Columns, Tables, Views, Materialized views in Scaleway Postgres 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
- 01 Mirror campaign performance data into BI tools for outbound reporting across senders
- 02 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
- 03 Replicate the application database into a warehouse for analytics without writing custom pipelines
- 04 Back internal tools with the same Postgres instance while Stacksync keeps it consistent with external systems
Common sync patterns
React to changes as they happen
Updates in Lemlist arrive as row changes in Scaleway Postgres, so triggers, jobs, and services can respond in near real time.
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 Scaleway Postgres; join them, index them, and use them in application logic without touching the vendor API.
What you can sync between Lemlist and Scaleway Postgres
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 | Scaleway Postgres objects | How this pairing syncs | |
|---|---|---|---|
| Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | Leads is specific to Lemlist and Tables to Scaleway Postgres — each maps to any object or custom field on the other side. | |
| Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Views Read-only sources for shaping data before it leaves the database. | Activities is specific to Lemlist and Views to Scaleway Postgres — each maps to any object or custom field on the other side. | |
| Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | Unsubscribes is specific to Lemlist and Materialized views to Scaleway Postgres — each maps to any object or custom field on the other side. | |
| Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Schemas Namespace tables so multiple applications or environments can be synced selectively. | Webhooks is specific to Lemlist and Schemas to Scaleway Postgres — each maps to any object or custom field on the other side. | |
| Team Members Sender and seat records map outreach activity to reps in other systems. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | Team Members is specific to Lemlist and Sequences to Scaleway Postgres — each maps to any object or custom field on the other side. | |
| Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | Campaigns is specific to Lemlist and Columns to Scaleway Postgres — each maps to any object or custom field on the other side. |
How changes propagate between Lemlist and Scaleway Postgres
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Lemlist Scaleway Postgres Sub-second propagation
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.
DeliveryEach detected change is applied to Scaleway Postgres as a row-level write, with types converted between the two schemas.
Scaleway Postgres Lemlist Sub-second propagation
DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Lemlist: Subject to the platform's API rate limits.
- Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.

FAQ
Lemlist and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Lemlist and Scaleway Postgres: authenticate both systems, choose the objects to sync (such as Lemlist's Leads and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Lemlist: REST API. Authentication: API key. Scaleway Postgres: SQL wire protocol (PostgreSQL). Authentication: Database credentials (username/password over TLS). Stacksync manages authentication, retries, and rate limits on both sides.
-
Lemlist: Activity events such as replies, opens, bounces, and unsubscribes can be delivered via webhooks, enabling near real-time updates to CRM records without polling every campaign. Scaleway Postgres: Scaleway operates data centers in European regions, which matters for teams with EU data residency requirements. Stacksync's field mapping accounts for these differences between Lemlist and Scaleway Postgres without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Lemlist and Scaleway Postgres records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Lemlist and Scaleway Postgres connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Lemlist–Scaleway Postgres integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Lemlist and Scaleway Postgres. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
