About the Book
Substack Mastery V2: A Practical Guide to Grow with Purpose, Write with Confidence, and Build a Loyal Audience Empowered by the New P.I.L.L.A.R.(TM) Framework Insights for ADVANCED Freelance Writers, Book Authors, and Content Startups
When I first shared what I had learned about writing on Substack, I wanted to help other writers find their footing, just as I had struggled to do so myself. My early version of Substack Mastery focused on practical steps: how to write better posts, build a mailing list, and understand the platform. It helped thousands of writers to start Substack successfully, which delighted me.
However, as more new writers reached out to say they were still overwhelmed or unsure how to grow their audiences and start earning a reasonable income via their newsletters, I realized that previous strategies and tactics alone were not enough. I needed something more radical to make a lasting impact and support fellow writers on Substack.
That is what led me to create the P.I.L.L.A.R.(TM) Framework. It is a conceptual and practical system I developed after making numerous mistakes, starting over multiple times, and rebuilding everything with greater intention, which helped me achieve my goal on Substack and other platforms I integrated. I introduced those platforms, including Patreon, Medium, Kit, WordPress, and others.
This new approach helped me grow my Substack audience from around 30,000 to over 239,000 subscribers between 2024 and 2025, and I became a best-selling author on Substack even though it was not my intention. This success was not achieved through viral tricks but rather by consistently aligning my content with purpose, values, and clarity covered in the P.I.L.L.A.R.(TM) Framework.
And it has now helped thousands of other writers find their voice and build real communities around their work.
This new book is my way of passing that learning forward. If you are feeling invisible, burnt out, or unsure how to grow without selling your soul or spending hours doing things that do not feel right, this new version of Substack Mastery will meet you where you are.
I will walk you through the new PILLAR framework, additional strategies I've developed, real-world examples, common pitfalls, and ways to make your newsletter work on your terms. And if you're tired of all the hype out there, I wrote this as its opposite. I am a realistic and pragmatic optimist.
In this new book, you will also get a preview of the Substack Mastery Boost Pilot initiative I am quietly building with our growing community. It is a low-cost, writer-first platform designed for education and marketing, supporting ethical growth, reader discovery, and mutual learning in 2026 and beyond.
I believe we do not need to chase algorithms to succeed. We need a structure we can trust, a rhythm we can sustain, and a community that lifts us as we grow.
More importantly, I focus on making our readers happy with high-quality and valuable content. I factored in all these key success factors in this book and simplified the concepts and practices with relatable and memorable examples.
That is what Substack Mastery V2 offers to take your writing business to the next level. You are welcome to join my supportive and joyful community on Substack, Medium, Patreon, and other platforms to shine. I wish you the best in your writing journey.
