Why teams connect GitHub and Lemlist

Stop re-entering the same information in GitHub 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 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.

Common use cases

  • 01 Sync organization and team membership with an identity or HR system to automate access reviews and offboarding.
  • 02 Create GitHub issues automatically from records written elsewhere, such as bug reports logged in a CRM case object.
  • 03 Stop or pause sequences automatically when a reply converts to a deal in the CRM
  • 04 Mirror campaign performance data into BI tools for outbound reporting across senders

Common sync patterns

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.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

Where Lemlist is where the team documents or plans: keep its data fed

Information that originates in GitHub stays current in Lemlist instead of going stale after a one-time paste.

What you can sync between GitHub 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.

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.

How changes propagate between GitHub 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.

GitHub Lemlist Sub-second propagation

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.

Rate-limit considerations

  • GitHub: Authenticated REST requests are limited to 5,000 per hour per user; GitHub Apps scale limits per installation.
  • Lemlist: Subject to the platform's API rate limits.
