Pros & Cons

Ghost

Pros

  • Ghost takes no percentage of membership revenue, unlike Substack's 10% fee, so publishers pay only the plan price and Stripe fees.
  • Website, newsletter, and paid memberships work together without plugins.
  • The open-source core can be self-hosted for free, and APIs and webhooks support custom builds.
  • More than 100 listed integrations, including Zapier, Stripe, Mailchimp, and privacy-focused analytics tools.

Cons

  • Email features are basic: segmentation is limited and there is no built-in A/B testing or SMS.
  • Email delivery depends on Mailgun, which users say can be costly or unreliable when self-hosting.
  • Lower plans get email-only support with no weekend coverage, and Trustpilot reviews complain about billing and refunds.
  • The Starter plan excludes paid subscriptions, custom themes, and integrations.

Mailgun

Pros

  • Reviewers repeatedly praise the REST API and documentation as quick for developers to integrate.
  • Deliverability and detailed per-domain searchable logs get strong marks from users.
  • SOC 2 Type II and ISO 27001 certification, with 2FA, SAML SSO and AES-256 encryption at rest.
  • A low entry price and a free tier of 100 emails a day for testing.

Cons

  • It is API-first and complicated for non-technical users, with a dated dashboard where settings and logs can be hard to find.
  • Several 2025 reviews report automated account suspensions with little warning.
  • Short log retention on lower plans (1 day on Free and Basic).
  • Reviewers call it costlier than rivals once volume grows, and inbox placement tools are a separate product.
