ConvertKit
ConvertKit, now rebranded as Kit, is an email marketing platform built specifically for online creators including bloggers, course sellers, newsletter writers, and indie software developers, available via web browser. Its visual automation builder constructs multi-step sequences based on subscriber tags, form submissions, link clicks, and purchase events. Subscriber tagging and segmentation allow highly targeted broadcasts without managing separate lists. The Creator Commerce features allow selling digital products and paid newsletters directly through ConvertKit without a separate payment platform. The free plan supports up to 10,000 subscribers with limited automation. ConvertKit is used by individual creators and indie businesses who need more sophisticated audience segmentation and creator-specific commerce features than general-purpose email platforms provide.
