Understanding Newsletter Economics

Paid Subscription Models

The foundation of newsletter monetization is the paid subscription model. Typical conversion rates from free to paid subscribers range from 2-10%, with 5% being a common benchmark. Pricing typically ranges from $5-15 per month or $50-150 annually, with annual subscriptions offering better value and lower churn.

  • Beehiiv: No revenue share on subscriptions (flat monthly fee for premium features)
  • Ghost: No revenue share (self-hosted or flat monthly fee)
  • ConvertKit: Variable fees based on plan and subscriber count

Revenue Diversification

Newsletter Sponsorships

Sponsorships typically pay based on CPM (cost per thousand opens) or flat rates. Industry rates range from $25-75 CPM for general newsletters to $100-200+ CPM for specialized B2B or finance newsletters. Consistent open rates above 40% attract premium sponsors.

Affiliate Marketing

Product recommendations and affiliate links can generate substantial passive income. Success depends on audience trust and relevance of promoted products. Typical affiliate commissions range from 5-30% depending on the product category.
