Why teams connect Lemlist and PostgreSQL
Mirror Lemlist's data into PostgreSQL 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 PostgreSQL.
Stacksync mirrors Activities, Unsubscribes, Webhooks, Team Members from Lemlist into Columns, Primary and Unique Keys, JSONB Columns, Sequences in PostgreSQL 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
- Mirror campaign performance data into BI tools for outbound reporting across senders
- Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
- Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
- Let an application write to its own database and have those rows appear as records in business systems in near real time
Read Lemlist with a query
Records from Lemlist are ordinary rows in PostgreSQL; 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 PostgreSQL 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 PostgreSQL, so triggers, jobs, and services can respond in near real time.
What you can sync between Lemlist and PostgreSQL
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 | PostgreSQL objects | |
|---|---|---|
| Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. | |
| Team Members Sender and seat records map outreach activity to reps in other systems. | JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. | |
| Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Sequences Generate surrogate keys for rows created by inbound syncs. | |
| Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. | |
| Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. | |
| Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Views Read-side projections used to expose joined or filtered data to a sync. |

FAQ
Lemlist and PostgreSQL integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Lemlist and PostgreSQL: authenticate both systems, choose the objects to sync (such as Lemlist's Webhooks and Team Members), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Lemlist and PostgreSQL: Read Lemlist with a query; Automate Lemlist from your codebase; React to changes as they happen. Records from Lemlist are ordinary rows in PostgreSQL; join them, index them, and use them in application logic without touching the vendor API.
-
Lemlist: REST API. Authentication: API key. PostgreSQL: SQL wire protocol (PostgreSQL frontend/backend protocol). Authentication: Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user. Stacksync manages authentication, retries, and rate limits on both sides.
-
Lemlist: Lemlist's data model attaches leads to campaigns, so cross-campaign views of a prospect are assembled by the consuming system rather than provided natively, which makes CRM sync the practical system of record. PostgreSQL: Logical decoding of the write-ahead log (wal_level=logical) provides row-level change capture without adding triggers to user tables. Stacksync's field mapping accounts for these differences between Lemlist and PostgreSQL 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 PostgreSQL records are not retained after a sync operation.
