🔧 Workflow

AI agents daily scrape industry trends, competitor newsletter content, and user community questions to generate initial drafts. After manual review for data accuracy and content value, content is automatically distributed to Substack and Beehiiv via RSS automation tools. Free content attracts new users to private channels, while paid columns, native ads, and brand partnerships drive revenue. Weekly reviews of open rates and conversion rates inform adjustments to vertical topics.

🛠 Setup Requirements

Requires familiarity with Substack and Beehiiv platform rules and basic formatting, as well as proficiency in prompt engineering. Use automation tools like Make.com or IFTTT to build distribution pipelines. No coding skills required; setup takes 3-4 weeks. The core strategy is to validate a single-month paid conversion model in one vertical before scaling.

💰 Revenue

① Paid Subscriptions (Primary): Readers pay monthly or annually. Estimated monthly revenue of $5,000-$20,000, with subscriptions accounting for 60% ($3,000-$12,000/month). ② Platform Native Ad Revenue: Advertisers pay the platform, which shares revenue based on impressions. Estimated at 30% of total revenue ($1,500-$6,000/month). Top creators can exceed $20,000/month. ③ Brand Partnerships: Brands pay $2,000-$5,000 per sponsored post, accounting for 10% of revenue. ④ Opportunity - AI Automation Services & Corporate Training: Charging SMEs per project or monthly. Enterprise solutions range from ¥5,000-¥50,000 per project, with annual earnings of ¥200,000+, and long-term consulting at ¥5,000-¥15,000/month.

💸 Cost

Fixed monthly costs are approximately $120 to $250, including AI model API calls (~$50), automation tool subscriptions (~$30), and domain/email service fees (~$40). No additional labor costs.

⏱ Time Investment

2 to 3 hours daily: 1 hour for manual review and adjustment of AI-generated content, 1 hour for user interaction and data analysis, and the remaining time for topic research.

🚀 Getting Started

First, select a vertical niche you are familiar with that has high user willingness to pay (e.g., AI tool reviews, creator economy, cross-border e-commerce). Register a free Substack account, publish 7 high-quality vertical posts, and enable paid subscriptions after reaching 1,000 free subscribers. Once the model achieves a customer acquisition cost (CAC) under $1 and a conversion rate over 3%, replicate it on Beehiiv.

🔑 Keys to Success

✅ Precise vertical selection with high scarcity and practical value, solving real pain points for specific users.
✅ Dual-platform distribution to maximize traffic coverage, tailoring content presentation to different platform user attributes.
✅ Building a tiered content system: free content as a traffic funnel, paid content for deep value delivery.
✅ A hybrid mechanism of AI-automated production/distribution combined with manual review to balance efficiency and content quality.

⚠️ 风险

⚠️ Platform policy changes affecting recommendation traffic or limiting paid features, impacting revenue stability.
⚠️ Lower-than-expected reader willingness to pay or user churn due to content homogenization in the vertical.
⚠️ AI-generated content becoming too generic, lacking competitive differentiation, and failing to retain paid users long-term.
⚠️ Overseas tax compliance risks; platforms like Substack may withhold taxes, requiring proper reporting to avoid penalties.
