Kit

Kit, the platform formerly known as ConvertKit, is an email marketing hub built around creators — writers, podcasters, course sellers, and YouTubers. Beyond sending newsletters, Kit's strength is its visual automation builder: tag subscribers by behavior, branch sequences by interest, and run evergreen funnels that sell products while you sleep. Landing pages, forms, and a Creator Network for cross-promotion handle audience growth, while Commerce features let you sell digital products and paid newsletters with no separate storefront. The free plan now supports up to 10,000 subscribers, making Kit unusually generous for starting out. Compared to newer publications-focused tools like beehiiv, Kit leans toward marketing automation depth: it's less about publishing a media brand and more about running a creator business on email.
