And How They Scale Their Publishing Business with Global Collaboration
Dear Subscribers,
Earlier today, our chief editor Dr Mehmet Yildiz published Chapter 18 of his best-selling book Substack Mastery for free for our community. His goal is, while educating our community, to obtain feedback from beta readers to improve the quality of this exceptional book for next versions and make it a valuable tool for our community and beyond.
As the editors and curators of ILLUMINATION publications on Medium and Substack, we found this comprehensive chapter helpful and converted it into a 15-minute interactive podcast using Google’s NKLM tool for busy people so that they can quickly understand the value and benefits of this important and easy-to-use tool.
Dr Yildiz believes that Reedsy might take newsletters of book authors to another level. Yesterday, he posted a poll from his Content Strategy, Development, & Marketing Insights newsletters. If you are interested, you may participate in this poll and share your experience with Reedsy.
Purpose of Chapter 18 in Substack Mastery Book
In this chapter, you will get a summary of his manuscript designed to onboard freelance writers and content entrepreneurs to Reedsy, highlighting compelling reasons for this and covering the pros and cons independently. While he crafted this chapter primarily for advanced writers and published authors, aspiring writers on Substack who are thinking about writing a book may also find it helpful. His goal is to introduce another powerful tool for Substack writers to consider — one that you can embrace if it aligns with your needs and aspirations or set aside if it doesn’t. I am simply a messenger and strategist offering you options to choose from.
