Narrareach is the production distribution layer for newsletter writers who want the outcome behind substack api webhooks without maintaining the full integration stack.
- Cloud scheduling for Substack Notes and social posts.
- Cross-posting from newsletter ideas into LinkedIn, Medium, X, Bluesky, and Threads.
- Platform-specific formatting and post previews.
- Retry handling and delivery status.
- Writer-friendly workflows that do not require maintaining an MCP server or REST API.
- Analytics and attribution loops after publishing.
Start with Substack API Webhooks on Narrareach.
Use your own MCP server or REST API for internal drafts, custom agent workflows, and proprietary business logic. Use Narrareach for the parts that need reliability: scheduling, account connections, publishing, retries, and performance feedback.
