Kortex) " subtitle: "Recap from Creator Growth Summit | March '25" published: 2025-03-06 --- # How to Use AI in Your Newsletter Writing Workflow (ft. Kortex) Let’s be real — writing newsletters can feel like staring into the abyss of a blank Google Doc. Whether you’re a seasoned creator or just starting out, the process can be frustrating, time-consuming, and downright uninspiring. That’s why we were pumped to sit down with Joey Justice, co-founder of Kortex, who’s not only built a killer writing app but has also written over 600 viral Twitter threads as a ghostwriter. [Embedded video](https://youtube.com/embed/Fow0AmxFq8o) In this post, we’re pulling back the curtain on his exact process, AI prompts included, so you can finally write newsletters people actually want to read (and maybe even grow your audience along the way). ## Table of Contents - [Key Timestamps](#key-timestamps) - [Top 6 Takeaways and Next Steps](#top-6-takeaways-and-next-steps) - [Key Resources & Tools Mentioned](#key-resources-tools-mentioned) - [Closing Note](#closing-note) ## **Key Timestamps** **Getting started 👇** 00:00 - What we'll be covering 01:57 - Understanding Kortex: Features and capabilities **Tools for your creative process** 🧠 04:55 - AI prompts for writing assistance 12:09 - Tips for social media growth 20:41 - Writing the perfect prompt 25:17 - Insights from Dan Koe 29:00 - Engagement metrics: Tracking what works 32:42 - Building an outline for your newsletter with AI **Q&A 🙋🏻‍♂️** 39:24 - Making your content stand out 42:33 - The ideal posting cadence 44:15 - Creators to follow ## **Top 6 Takeaways and Next Steps** **1\. Capture, Curate, Connect, Create** **Next Step:** Set up a system (like Kortex or Notion) where you can store inspiration, notes, and resources. The more organized your “second brain,” the easier writing becomes. **2\. Start with Your “Big Idea”** **Next Step:** Before you write, spend 5 minutes identifying the core message you want to share. Who’s your audience? What problem are you solving? Write this down in every draft. **3\. Use AI to Break Through Writer’s Block** **Next Step:** Use Joey’s newsletter prompts in ChatGPT, Claude, or Kortex to brainstorm topics and create outlines in minutes. **4\. Write to Your Former Self** **Next Step:** Make a list of struggles you’ve overcome and lessons you’ve learned. This is your content goldmine — your audience is probably dealing with the same stuff. **5\. Repurpose Like a Pro** **Next Step:** Turn your newsletter into a Twitter thread (listicle style works best), a LinkedIn post, and an Instagram carousel. One idea = multiple platforms. **6\. Track What Works — Then Do More of That** **Next Step:** Use Twitter’s [Advanced Search](https://twitter.com/search-advanced?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) or tools like Typefully to find your top-performing posts. Save them in a “greatest hits” folder to study what worked and repeat the formula. ## **Key Resources & Tools Mentioned** • [Kortex](https://www.kortex.co/?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [Readwise](https://readwise.io?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [ChatGPT](https://chat.openai.com?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [Claude](https://claude.ai?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [Typefully](https://typefully.com?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [Twitter Advanced Search](https://twitter.com/search-advanced?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) • [Dan Koe’s YouTube Channel](https://www.youtube.com/@DanKoe?utm_source=beehiivblog.beehiiv.com&utm_medium=referral&utm_campaign=how-to-use-ai-in-your-newsletter-writing-workflow-ft-kortex) ## **Closing Note** Joey’s message is clear — in a world where anyone can write with AI, **quality and personality win**. Tools like Kortex and ChatGPT can make your process faster (Joey’s prompts alone can save you hours), but the real magic happens when you write from experience, add your unique spin, and aren’t afraid to have a strong opinion. If you want to write newsletters that actually matter — and grow your audience along the way — start by writing to your former self. Capture the lessons you wish you had years ago, package them with some personality, and share them consistently across platforms.
