What is Substack and how does it work?
Substack hosts your newsletter: a publication site, email sending, paid subscription billing through Stripe, podcast and video hosting, subscriber chat, and Notes (its social feed). You write, set a price for premium content if you want one, and Substack handles delivery and payments. Its recommendation system lets publications endorse each other, which has become a real subscriber acquisition channel.
Substack standout strengths
Substack is the only newsletter platform where the network genuinely grows your list. Recommendations, Notes, and reader-app discovery compound — mid-sized publications routinely attribute a large share of new subscribers to it. The zero-fixed-cost model also removes all risk from starting: you pay nothing until readers pay you.
Substack weaknesses and drawbacks
The 10% take is steep at scale — a newsletter doing $100k/year hands over $10k, which buys a lot of beehiiv or Ghost hosting. Email tooling is deliberately minimal: no real automations, weak tagging, basic A/B options. And Substack's strategic drift toward being a social platform means it increasingly mediates your reader relationships through its app rather than your inbox.

Substack review: final verdict
