ConvertKit (Kit)

ConvertKit, rebranded as Kit in 2024, is the email marketing platform of choice for bloggers, YouTubers, podcasters, course creators, and independent publishers. Unlike traditional ESPs focused on business newsletters, ConvertKit is designed around the specific needs of content creators: building subscriber relationships, automating content delivery sequences, selling digital products and courses, and growing an audience through referral programs and landing pages. The platform uses a tag-and-segment approach to audience management rather than traditional list-based segmentation, giving creators more flexibility in targeting subscriber groups based on interests and behavior. ConvertKit's visual automation builder lets creators design subscriber journeys that branch based on email opens, link clicks, product purchases, or segment membership. The commerce features allow creators to sell digital products, subscriptions, and tip jars directly within the platform. In 2026, ConvertKit added an AI writing assistant for email copy, improved its newsletter discovery through the Creator Network, and expanded its sponsorship marketplace connecting creators with brand partners. The free plan covers up to 10,000 subscribers, making it the most generous in its category.
