Two-way sync
Changes in GitHub or Lemlist instantly reflect in both systems. No stale data, no manual imports.
Keep GitHub and Lemlist in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Releases, Workflow runs (Actions), Organizations and Teams, Users in GitHub with Unsubscribes, Webhooks, Team Members, Campaigns 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.
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
Information that originates in GitHub stays current in Lemlist instead of going stale after a one-time paste.
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.
| GitHub objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| Workflow runs (Actions) CI results synced into incident and reporting systems. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Workflow runs (Actions) is specific to GitHub and Leads to Lemlist — each maps to any object or custom field on the other side. | |
| Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Organizations and Teams is specific to GitHub and Activities to Lemlist — each maps to any object or custom field on the other side. | |
| Users Author and assignee identities matched to internal directories. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Users is specific to GitHub and Unsubscribes to Lemlist — each maps to any object or custom field on the other side. | |
| Labels and Milestones Classification fields mapped to statuses and sprints in external trackers. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Labels and Milestones is specific to GitHub and Webhooks to Lemlist — each maps to any object or custom field on the other side. | |
| Repositories Top-level containers whose metadata and settings syncs read to scope other objects. | Team Members Sender and seat records map outreach activity to reps in other systems. | Repositories is specific to GitHub and Team Members to Lemlist — each maps to any object or custom field on the other side. | |
| Issues Synced two-way with project trackers and support tools, including labels and assignees. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Issues is specific to GitHub and Campaigns to Lemlist — each maps to any object or custom field on the other side. |
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.
DetectionGitHub notifies Stacksync of record changes through webhook events. Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every GitHub–Lemlist connection.
Changes in GitHub or Lemlist instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever GitHub or Lemlist data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single GitHub or Lemlist record.
Track your GitHub ⇄ Lemlist sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between GitHub and Lemlist.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate GitHub and Lemlist with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the GitHub and Lemlist objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between GitHub and Lemlist: authenticate both systems, choose the objects to sync (such as GitHub's Workflow runs (Actions) and Organizations and Teams), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for GitHub and Lemlist: Where both tools track people or companies: one consistent record; Where one tool produces events: mirror them in the other; Where Lemlist is where the team documents or plans: keep its data fed. Contact and company details corrected in either tool update the other, so nobody works from the old version.
GitHub: REST API and GraphQL API. Authentication: OAuth 2.0, fine-grained personal access tokens, or GitHub App installation tokens. Lemlist: REST API. Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.
GitHub: GitHub Apps authenticate with short-lived installation tokens scoped to specific repositories and permissions, which suits least-privilege sync setups. 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. Stacksync's field mapping accounts for these differences between GitHub and Lemlist 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 GitHub and Lemlist records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed GitHub and Lemlist connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom GitHub–Lemlist integration in-house.
