But with so many niches already saturated, how can you find a unique angle that resonates with readers and earns you a steady income? Here are 10 niche ideas for Substack newsletters, complete with potential monthly earnings:

  1. Personal finance for creatives ($1,000+ per month) Are you an artist or writer who struggles with money management? Share your journey and tips for financial stability in a creative field.
  2. Environmental sustainability for families ($500+ per month) Parents are increasingly concerned about the impact of their lifestyle on the planet. Create a newsletter that offers easy-to-implement tips and resources for sustainable living.
  3. Plant-based cooking for beginners ($2,000+ per month) The vegan lifestyle is gaining popularity, but many people feel intimidated by the prospect of giving up meat and dairy. Simplify the process with beginner-friendly recipes and advice.
  4. Esports news and analysis ($5,000+ per month) The esports industry is booming, and fans are hungry for insider knowledge and analysis. Build a newsletter that covers the latest developments in esports and offers expert commentary.
  5. Health and wellness for travelers ($1,500+ per month) Travel can be stressful and disrupt healthy habits. Create a newsletter that helps readers stay fit, well-rested, and nourished while on the go.
  6. Mental health for entrepreneurs ($3,000+ per month) Starting and running a business can take a toll on mental health. Share your experiences and offer advice for managing stress, anxiety, and burnout.
  7. Sustainable fashion for plus-size women ($2,000+ per month) The fashion industry often neglects the needs and preferences of plus-size women. Create a newsletter that highlights ethical and sustainable clothing options in larger sizes.
  8. Science education for kids ($4,000+ per month) Parents and educators are always looking for engaging and accessible ways to teach science to young learners. Create a newsletter that provides fun experiments, activities, and facts.
  9. Podcasting tips and tricks ($3,500+ per month) Podcasting is a popular medium, but it can be difficult to stand out in a crowded field. Share your expertise in podcast production, promotion, and monetization.
  10. Social media marketing for non-profits ($2,500+ per month) Non-profit organizations often struggle to reach and engage with their target audience on social media. Offer insights and strategies for effective social media marketing in the non-profit sector.
