Ghost vs Substack: Which Newsletter Platform Should You Run?

Ghost is open-source publishing software built specifically for newsletters and membership sites, with paid subscriptions, member management, and email delivery built into the core platform rather than bolted on. When self-hosted, Ghost connects directly to a payment processor for subscription billing, so the platform itself takes no percentage cut of what subscribers pay - the only fees are the payment processor's own standard rates.

That difference compounds at scale: a newsletter earning meaningful subscription revenue keeps all of it after payment processing, rather than handing a slice to the platform every month indefinitely. The cost instead shows up as a hosting bill and the setup time to get Ghost installed, configured, and connected to email delivery and payments correctly the first time.

Substack manages email deliverability entirely on its own infrastructure, which is convenient but also means the writer has limited visibility into deliverability issues and no control over the sending domain's reputation - it's shared across every Substack publication. Subscriber lists can be exported, but the writer is still building an audience inside someone else's ecosystem.

Self-hosted Ghost connects to a transactional email provider chosen by the writer, giving direct control over the sending domain and deliverability settings, plus full, ongoing access to the subscriber database rather than periodic exports. That ownership matters most to writers planning to build a long-term, independent brand around their newsletter rather than one tied to a single platform's ecosystem.
