Why teams connect Gainsight and Lemlist
Stop re-entering the same information in Gainsight and Lemlist: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Task and Playbook, Custom Objects, Company, Person (People) in Gainsight with Leads, Activities, Unsubscribes, Webhooks in Lemlist in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- 01 Keep Relationship records aligned with a billing system or ERP so multi-product customers map to the correct contracts and invoices.
- 02 Read Timeline Activities and Success Plan objectives into a reporting database for churn, QBR, and CSM-productivity dashboards.
- 03 Mirror campaign performance data into BI tools for outbound reporting across senders
- 04 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
Common sync patterns
Where Lemlist is where the team documents or plans: keep its data fed
Information that originates in Gainsight stays current in Lemlist instead of going stale after a one-time paste.
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
What you can sync between Gainsight and Lemlist
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.
| Gainsight objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| CTA (Call to Action) Risk and expansion alerts that drive CSM plays; often synced to ticketing or project tools so follow-up work is tracked where teams operate. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | CTA (Call to Action) is specific to Gainsight and Leads to Lemlist — each maps to any object or custom field on the other side. | |
| Scorecard Fact Health scores and measures per Company or Relationship; usage metrics from a warehouse are written in so scores reflect live telemetry. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Scorecard Fact is specific to Gainsight and Activities to Lemlist — each maps to any object or custom field on the other side. | |
| Timeline Activity Logged calls, emails, and notes; usually read out into a reporting database for QBR and churn analysis. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Timeline Activity is specific to Gainsight and Unsubscribes to Lemlist — each maps to any object or custom field on the other side. | |
| Success Plan Account objectives with associated tasks; read out for reporting or synced with project tools tracking onboarding and adoption. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Success Plan is specific to Gainsight and Webhooks to Lemlist — each maps to any object or custom field on the other side. | |
| Task and Playbook Cockpit tasks generated from CTAs and playbooks; synced with Jira or Asana so execution happens in the team's own tool. | Team Members Sender and seat records map outreach activity to reps in other systems. | Task and Playbook is specific to Gainsight and Team Members to Lemlist — each maps to any object or custom field on the other side. | |
| Custom Objects Org-specific MDA tables with the __gc suffix; discoverable via the Describe API so field mappings can be generated automatically. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Custom Objects is specific to Gainsight and Campaigns to Lemlist — each maps to any object or custom field on the other side. |
How changes propagate between Gainsight and Lemlist
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.
Gainsight Lemlist Interval-based propagation
DetectionStacksync polls Gainsight for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the ModifiedDate (GS Modified Date) system field, which is filterable and sortable on every object.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Lemlist Gainsight Sub-second propagation
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.
DeliveryEach detected change is written to Gainsight through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Gainsight: Synchronous APIs are capped near 100 calls/min and 50,000/day; the asynchronous Bulk API allows 10 calls/hour and 100/day. Both are fixed-window limits, and the applicable per-hour and per-day limits are returned in the x-ratelimit-limit response header.
- Lemlist: Subject to the platform's API rate limits.

FAQ
Gainsight and Lemlist integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Gainsight and Lemlist: authenticate both systems, choose the objects to sync (such as Gainsight's CTA (Call to Action) and Scorecard Fact), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Gainsight and Lemlist connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Gainsight–Lemlist integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Gainsight and Lemlist. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Gainsight: Polling on the ModifiedDate (GS Modified Date) system field, which is filterable and sortable on every object; Rules Engine Real-Time Rules can optionally push specific object events (e.g., a Company stage change) to an external endpoint. On Lemlist: Webhooks on outreach activity events, plus polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Gainsight side: Task and Playbook, Custom Objects, Company, Person (People), plus custom fields where Gainsight exposes them. On the Lemlist side: Leads, Activities, Unsubscribes, Webhooks. Stacksync auto-detects both schemas and converts types between the two systems.
-
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.
