How Kevin Indig Transforms a Single Newsletter Issue Into a Week of Content
Published on September 24, 2026
Kevin Indig leverages strategic repurposing and AI integration to maximize the reach of his Growth Memo, turning one week’s worth of deep research into multiple days of distributed content for his 29,000+ subscribers.
Key Takeaways
- Repurpose Deep Research: Treat one comprehensive newsletter issue as multiple shareable assets, such as charts, findings, or discussion questions.
- Validate Ideas First: Use Substack Notes to test topics and gather feedback before committing weeks of time to a full article.
- Automate Distribution: Use scheduling tools to batch-process posts, saving 2–3 hours per week for creators who are rarely at their desks.
- Leverage AI for Insights: Connect coding assistants like OpenAI’s Codex to your publishing history via MCP to identify high-performing topics.
- Build Sustainable Routines: Focus on creating a repeatable distribution routine that fits your workflow, whether you have zero or 30,000 subscribers.
The Strategy: From One Memo to Seven Days of Content
Indig’s core philosophy is that a single Growth Memo provides several distinct opportunities for engagement. Rather than letting the content sit after publication, he extracts specific elements to share separately. "A single Memo gives us several things to share," he notes. These assets might include a compelling chart, a surprising data finding, or a provocative question designed to spark discussion among his audience.
This method ensures that the significant time invested in research pays off over a longer period. Instead of one day of attention followed by silence, the content continues to generate interest throughout the week. This is particularly effective for Indig, who spends days on each piece. By breaking down the newsletter into smaller, digestible units, he maintains consistent visibility with his readership without creating new content from scratch every day.
Testing Ideas with Substack Notes
Before diving into the full research process, which consumes an entire week of Indig’s time, he uses Substack Notes to validate potential topics. This platform allows him to post short takes, charts, videos, and teasers for Memo articles that have not yet been published. It serves as a low-effort testing ground where ideas can be gauged for interest.
A fully researched article requires substantial effort, whereas a Note only takes a few minutes to produce. Indig emphasizes that investing in these shorter formats first is well worth the time. The insights generated from his original research, client conversations, and data patterns feed directly into this testing phase. If a Note performs well, it often becomes the foundation for an entire newsletter issue. This iterative process ensures that the final long-form content aligns with what his audience actually wants to read.
Automating Distribution with
While Substack Notes helps create and test content, a scheduling platform is essential for distribution. This tool is critical because Indig is rarely at his desk. His schedule is often filled with travel or back-to-back client meetings.
He can crosspost content to X, LinkedIn, Threads, and Bluesky, ensuring that every Memo gets distributed without requiring him to be online for every individual post. This time savings allows him to focus on high-value activities like research and client advisory work rather than manual posting.
Integrating AI with Model Context Protocol
Indig’s favorite feature within his tech stack is the Model Context Protocol (MCP) integration. He specifically uses OpenAI’s Codex, a coding assistant, to analyze his own post history.
By pointing Codex at his historical data, he can identify which posts landed most effectively with his audience. This data-driven insight helps him pull ideas for what to write next, ensuring that future content is informed by past performance. "I love the MCP," Indig states.
Advice for Substack Creators
For writers who are still deciding whether they need a dedicated tool at all, Indig’s advice remains foundational: start where your readers already are, build a routine you can keep, and check what’s working so you can repeat it or move on. This guidance applies equally to someone just starting on Substack with zero subscribers as it does to those with 30,000.
The specific tools—such as a scheduling queue or a coding assistant—are secondary to the routine itself. It is the consistency of the distribution strategy that drives results. By combining original research, idea validation through short-form posts, automated scheduling, and AI-driven insights, creators can transform a single piece of work into a week-long engagement cycle. This approach not only saves time but also maximizes the impact of every hour spent creating content.
