What is Kit (ConvertKit)?
Creator-focused email marketing platform for newsletters, digital products, and audience growthKit, formerly known as ConvertKit, is an email marketing and audience growth platform designed specifically for creators including writers, podcasters, musicians, YouTubers, and course creators. The platform provides a visual automation builder for creating sophisticated email sequences, a landing page and form builder for growing subscriber lists, commerce tools for selling digital products and paid newsletters, and a creator network for cross-promotion with other creators in complementary niches. Kit focuses on deliverability and subscriber relationship management rather than flashy design templates, reflecting its philosophy that creator emails should feel personal rather than corporate. The tag-based subscriber management system allows flexible segmentation based on interests, behaviors, and purchase history without the rigid list-based approach of traditional email marketing tools. Kit Commerce enables creators to sell digital products, courses, and paid newsletter subscriptions directly through the platform with no additional tools needed.
