The economics of newsletter scaling

Substack takes 10% of all revenue from paid subscribers. Stripe also charges 2.9% plus 30 cents plus an additional 0.7% for recurring billing. If a subscriber pays $10 monthly, the combined Substack and Stripe fee totals $1.66 per person. A publisher with 100 subscribers paying $10 each monthly pays $166 in fees, which adds up to $1,992 in total fees every year for that small cohort. If subscribers pay through the Substack iOS app, Apple takes an additional cut of up to 30% on top of the 10% platform fee. A custom domain requires a one-time $50 fee on Substack.

WordPress plugin and hosting costs

WordPress allows control over expenditure because publishers choose their own hosting and email services. Bluehost provides hosting for $2.99 per month. For email, Brevo costs $9 per month to send up to 5,000 emails, while Constant Contact starts at $12 per month. You know the basics of managing self-hosted software already. Membership plugins replace the platform take with annual or monthly subscriptions. MemberPress costs approximately $199.50 for an introductory year and allows content restriction based on subscription plans. Paymattic costs $59 per year and uses a drag-and-drop form builder. Simple Membership provides a free version.

WordPress is clearly the better economic choice for growing subscription businesses. A publisher with 100 subscribers paying $10 monthly spends between $350 and $500 annually on hosting, email, and MemberPress. This results in a saving of over $1,400 compared to Substack. Everest Forms costs $49 per year and supports recurring payments. User Registration & Membership costs $79 per year. Easy Digital Downloads costs $99 per year and handles multi-currency and discount codes. Paid Memberships Pro offers a free core version. Ultimate Member costs $276 per year. Restrict Content Pro costs $299 per year. S2Member provides a Pro version with a one-time cost of $89. Will the high commission rates eventually push all independent creators toward self-hosted solutions?

Payment processing and automation math

Stripe handles online payments with a 2.9% plus 30 cents flat rate. For businesses with monthly card volume above $30,000, Payment Depot provides lower costs through a membership model of $79 to $199 per month plus interchange plus a fixed per-transaction markup of $0.05 to $0.15. A merchant processing $250,000 in monthly volume typically saves $1,500 to $2,000 per month by moving from Stripe’s flat rate to Payment Depot’s interchange-plus structure, modeled against a standard U.S. card mix of 60 percent debit and 30 percent rewards consumer credit.

Email automation relies on how well a platform connects to Stripe. Klaviyo triggers flows directly on payment events like customer.subscription.created without middleware. Klaviyo also uses purchase history and lifetime value to segment users and handles failed payment recovery and win-back sequences. ActiveCampaign connects to Stripe via e-commerce features and updates CRM Deals automatically when payment events fire. ActiveCampaign uses conditional branching for dunning. Kit suits creators because it triggers automations immediately upon successful purchases and tags subscribers based on the product purchased. Kit also manages subscription through Stripe billing. Mailchimp lacks real-time payment event triggers and requires the tool Make to listen for Stripe webhooks to trigger a Customer Journey.
