In their own words
Kit
Kit is an email-first operating system for creators, combining audience growth, email publishing, automation, and monetization. Landing pages, newsletter sites, forms, and creator recommendations help attract subscribers. Users can tag and segment subscribers by interests or behavior and personalize messages. A visual automation builder maps audience journeys, although several automation features are excluded from the free plan. Kit supports digital products, subscriptions, paid newsletters, and sponsorships. Its App Store groups integrations for e-commerce, memberships and courses, analytics, CRM, and workflows. API access is available on the Free plan, with API V4 for workflow automation and third-party connections. Kit lists a newsletter website, custom domains, paid subscriptions, unlimited email sending, and a sponsor marketplace. Plans include Free at free, Creator at $33 a month, and Pro at $66 a month. The Free plan supports up to 10,000 subscribers and one basic Visual Automation. A 14-day trial is also listed.
OpenEMM
OpenEMM is web-based open-source software for email marketing and automation, including newsletters and transactional or date-driven messages. Its tools include a campaign manager, calendar reminders and comments, responsive templates, recipient status history, and profile enrichment based on recipient reactions. It also provides bounce management, real-time opener and click statistics, behavior-based target groups, web forms, a multiqueue mail backend, web services, and a plugin interface. Integrations include Make and n8n, alongside HTTP request endpoints and import and export options. OpenEMM is self-hosted, with operation on a user's premises, through a hosting provider, or in a data center. The download page lists Linux servers and Windows or Mac servers via VirtualBox. From OpenEMM 2019 Spring, releases use the GNU AGPLv3 license. The plan costs nothing, with no limits on recipients, mailing lists, or dispatches. A three-day demo is available, but mailings cannot be sent from that account.
