Substack: Pros & Cons

Cons
- −The 10% platform fee plus Stripe's ~2.9% + $0.30 per transaction creates a 13-16% total take rate that becomes very expensive at scale (e.g., $1,300-$1,600/month on $10K revenue)

- −No public API and zero native third-party integrations — cannot connect to CRMs, e-commerce platforms, Zapier, or other marketing tools
- −Limited design customization with a single standardized template — no drag-and-drop editor, no custom HTML, and minimal branding options
