1 / 2The Story
Substack is a publishing platform where a writer can start a newsletter and charge for it. The platform handles the website, the email delivery, the payment, and the subscriber list, and it takes a cut of subscription revenue rather than charging a monthly fee.
The model is the reason it grew. A writer does not pay for software before earning anything: publishing is free and the platform's revenue comes from the subscriptions it processes. Paid and free subscribers can be on the same list, and a post can be public, free to subscribers, or paid-only.
The tradeoff is control and portability. The audience lives on Substack's network, the design is largely fixed, and the platform's recommendations surface other writers to your subscribers. Writers who want a custom domain, their own design, and an exportable list sometimes move to self-hosted publishing software.
Overview
Substack's commercial model is aligned with the writer's: the platform earns when a subscription is sold, not when software is bought.
A writer starts a publication at no cost. The platform provides the website, the email delivery, the subscriber list, and the payment processing, and it takes a percentage of subscription revenue. Because there is no upfront software cost, publishing a first post requires no financial decision.
Free and paid subscribers share one list, and each post can be public, free to subscribers, or paid-only. That lets a writer build an audience before introducing a paywall, and it lets a paywall apply to some posts rather than all of them.
The tradeoff is control. The audience lives on the platform's network, the design is largely fixed, and the recommendation system surfaces other writers to your subscribers. Writers who want a custom domain, a bespoke design, and a portable list sometimes move to self-hosted publishing software once the audience is established.
Key Features
- Free publishing
Starting a publication costs nothing, and the platform earns from subscriptions rather than a software fee.
- Paid subscriptions
Payment, recurring billing, and subscriber management are handled by the platform.
- Mixed free and paid posts
Each post can be public, free to subscribers, or paid-only, so a paywall can be introduced gradually.
- Built-in discovery
A recommendation network surfaces publications to readers, which is a distribution channel a self-hosted site lacks.
Where Substack is a strong choice, and where it is not
Choose Substack when the goal is to start publishing and charging for subscriptions without paying for software first, and the built-in discovery is useful.
Look elsewhere if the publication needs a custom domain with full design control and a portable subscriber list. Self-hosted publishing software offers that at the cost of running it.
