Frequently asked questions
How much should I spend before I have paying subscribers?
Under $30/mo. Beehiiv is free up to 2,500 subscribers. Claude at $20/mo is the only must-pay item. Buffer free tier covers your first 10 posts/month. Add Grammarly only when you start getting reader feedback on typos.
Can I swap Claude for ChatGPT?
Yes — both work. ChatGPT is better for image generation (DALL-E built in). Claude is better for long-form drafting and longer context. Most serious creators run both.
Why not Substack instead of Beehiiv?
Substack is fine for free newsletters but takes 10% of paid subscriptions. Beehiiv keeps the cut and has better growth tools (referral program, audience network) for free.
