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.
