ConvertKit

ConvertKit — rebranded as Kit — is an email marketing and audience-growth platform built specifically for creators: newsletter writers, course creators, YouTubers, podcasters, and solo businesses. Rather than a corporate marketing suite, it focuses on the creator workflow: growing a subscriber list with customizable landing pages and sign-up forms, sending broadcasts and newsletters, and building automated email sequences ("Visual Automations") triggered by subscriber behavior and tags.

The platform's model centers on a flexible, tag-based subscriber system rather than rigid lists, so a single subscriber can be segmented many ways and never double-counted. Beyond email, Kit includes landing pages, a creator network for cross-recommendations that grow audiences, paid newsletters and digital-product sales (Kit Commerce), and a sponsorship marketplace — extending it from an email tool into a broader platform for making a living as a creator. Deliverability, simplicity, and creator-friendly design are its calling cards.

Kit serves individual creators through established creator businesses. Pricing is subscriber-based: a generous Free plan (up to 10,000 subscribers with unlimited sends but no automations), a Creator plan that adds automations and integrations, and a Creator Pro plan that adds advanced reporting, subscriber scoring, and a newsletter referral system — with prices scaling by subscriber count (Creator around $29/month at 1,000 subscribers after a 2025 price change). It competes with Mailchimp, MailerLite, Beehiiv, Substack, and ActiveCampaign, differentiating on its creator focus and tag-based automations.
