Hybrid monetization in newsletter platforms

The winning newsletter platform is becoming the one that both charges creators for software and helps them make money inside the product. That changes the value proposition from pay us to send email, to use this system to grow subscribers, sell sponsorships, and reinvest that cash into more growth. Beehiiv made this clearest by pairing subscription software with ads and Boosts, while Kit added sponsor and recommendation networks, and Substack has been pulled toward ads as subscription revenue alone proved limiting.

• Beehiiv shows the hybrid model in its most explicit form. In May 2024, about 70% of revenue came from SaaS and 30% from ads. By June 2025, about a third of revenue came from Ad Network and Boosts, where brands buy placements and creators buy subscribers, with Beehiiv taking a cut.

• Kit used ads and recommendations less as a separate business line and more as a retention machine. Sponsor Network pays creators for inventory, Creator Network drives subscriber growth, and the combined effect pushed net dollar retention above 100%, because creators who earn and grow on platform are less likely to churn.

• Substack started as the clean opposite, a take rate business built around paid subscriptions and cultural prestige. But many larger writers were already selling ads manually, and by 2025 middle tier and larger writers were getting 20% to 60% of income from ads, which pushed Substack to build its own ad product to defend against lower take rate SaaS rivals.

This market is heading toward bundled creator operating systems. Software fees, sponsorship sales, paid recommendations, payments, and analytics will increasingly sit in one stack, because the platform that controls both workflow and monetization can justify higher effective pricing and lock in the best newsletters with a stronger grow, earn, reinvest loop.
