A side-by-side editorial comparison of Keila and Ghost — release velocity, themes, recent moves, and the top alternatives to consider.
Keila adds transactional emails and multi-format templates, broadening past pure newsletters
Keila, an open-source, privacy-focused newsletter tool, made a notable leap in v0.30.0: MJML/HTML/plain-text templates, reusable content slots, and transactional emails — a new product surface beyond bulk campaigns. Surrounding releases add manual contact-status control, API-driven contact events, pre-filled forms, more languages, and a new email scheduler that re-architected the messages schema to enable transactional sending.
Ghost keeps pushing from publishing into membership growth and lifecycle email.
Ghost ships weekly, and the recent run is concentrated on membership: automated email sequences, member segmentation, gift subscriptions, and community features like comment threading. The publishing core is stable; the active work is monetization and reader-relationship tooling. A separate non-product note flagged recognition by the Digital Public Goods Alliance.

The direction is clear: Keila is evolving from a newsletter sender into a more general email platform. The v0.20.0 scheduler/messages-schema rework laid the groundwork, and v0.30.0 cashed it in with transactional email and flexible templating. Internationalization and API/contact-lifecycle features show parallel investment in reach and automation.
Expect transactional email and content-slot templating to mature, with follow-on work on triggered/automated messages now that the messages schema supports them. Continued localization and contact-API expansion are likely.

Ghost is building the retention and growth loop around paid membership — onboarding sequences, saved segments, referral mechanics via gifting, and richer comments. Each release adds a piece a creator would otherwise buy from a separate email-marketing or community tool. The line between Ghost and a marketing-automation platform is narrowing.
The email-sequences feature is in beta; expect it to reach general availability with more trigger types and branching, extending Ghost further into drip-automation territory.
