Why teams connect GitHub and Resend

Stop re-entering the same information in GitHub and Resend: 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 Users, Labels and Milestones, Repositories, Issues in GitHub with Emails, Contacts, Audiences, Broadcasts in Resend 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 Mirror repository, PR, and workflow-run data into a Postgres database for engineering-metrics reporting.
  • 02 Sync organization and team membership with an identity or HR system to automate access reviews and offboarding.
  • 03 Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • 04 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.

Common sync patterns

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

Information that originates in GitHub stays current in Resend 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.

What you can sync between GitHub and Resend

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 Resend objects How this pairing syncs
Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Organizations and Teams is specific to GitHub and Email events to Resend — each maps to any object or custom field on the other side.
Users Author and assignee identities matched to internal directories. API keys Scoped credentials managed per environment for send and read access. Users is specific to GitHub and API keys to Resend — 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. Emails Sent messages retrievable by ID with current delivery status. Labels and Milestones is specific to GitHub and Emails to Resend — 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. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Repositories is specific to GitHub and Contacts to Resend — 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. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Issues is specific to GitHub and Audiences to Resend — each maps to any object or custom field on the other side.
Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. Broadcasts One-to-many campaign sends addressed to an audience. Pull Requests is specific to GitHub and Broadcasts to Resend — each maps to any object or custom field on the other side.

How changes propagate between GitHub and Resend

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 Resend 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 Resend through its API, with automatic retries and rate-limit backoff.

Resend GitHub Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.
