Kit

Kit (formerly ConvertKit) is the email marketing platform purpose-built for creators who want to monetize their audiences without complexity. Since 2013, Kit has served hundreds of thousands of content creators including podcasters, authors, YouTubers, coaches, and online course sellers with an email-first operating system designed specifically for creator economics. Unlike generic email tools like Mailchimp or Klaviyo designed for e-commerce, Kit understands the unique needs of indie creators and provides monetization capabilities right out of the box.

The platform's free Newsletter plan is exceptionally generous, supporting up to 10,000 subscribers with unlimited emails, forms, landing pages, and basic automation—a tier that many competitors reserve for paid plans. This free tier alone makes Kit accessible for indie creators just starting their audience-building journey. When you're ready to scale, the Creator plan starts at $29/month for 1,000 subscribers with professional features, and Creator Pro adds A/B testing, advanced engagement scoring, and affiliate network access. Pricing scales intelligently with your subscriber count, and annual plans receive roughly 16% discounts, making multi-year commitments economical.

What sets Kit apart is its built-in monetization ecosystem. You can sell digital products, manage subscriptions, and access the Kit Ads network for creator recommendations—all integrated directly into your dashboard rather than requiring third-party tools. The platform handles subscriber segmentation, engagement scoring, and automated sequences, empowering solopreneurs to personalize communication at scale without hiring a marketing team. You also get a 14-day free trial of pro features and a 30-day money-back guarantee, removing financial risk from upgrading.

Kit also provides free migration services for large subscriber lists and integrates with Zapier, WordPress, Shopify, Stripe, and other creator tools, fitting seamlessly into your existing tech stack. The community is vibrant and focused on creators rather than enterprise teams. While Kit isn't ideal for large enterprises, its cost-effectiveness, creator-centric feature set, and multiple monetization options make it the natural choice for indie authors, podcast creators, YouTubers, and coaches building sustainable audience-based businesses.
