What is Kit?

Kit, formerly ConvertKit, is an email marketing platform built specifically for creators — writers, YouTubers, podcasters, course sellers, and other independent professionals who make a living from their audience. Where general email tools treat every user the same, Kit is designed around the creator's journey of building, nurturing, and monetising a following. Its features, philosophy, and even pricing reflect a deep focus on helping creators turn an email list into a sustainable business, which has earned it a devoted following in the creator economy.

The platform centres on growing and engaging an audience through email. It offers customisable signup forms and landing pages to capture subscribers, powerful tagging and segmentation so you can treat different parts of your audience appropriately, and visual automations that send the right emails based on what subscribers do. Kit also includes commerce features that let creators sell digital products and subscriptions directly, plus tools for recommending and being recommended by other creators, all aimed at helping independent creators both reach more people and earn from their work without stitching together many separate tools.

Kit is used by creators of all kinds who see their email list as the foundation of their business and want a platform tailored to that reality. The value is creator-focused capability: powerful automation and audience tools combined with built-in monetisation, all designed around how creators actually work. Because email remains one of the most reliable and direct ways to reach an audience — unmediated by social algorithms — having a platform purpose-built to grow and monetise that audience is genuinely valuable. For any creator who wants to build a real relationship with their followers and turn it into income, Kit offers a thoughtfully designed, creator-first email marketing solution.

What is Substack?

Substack is a publishing platform that makes it simple for writers and creators to start a newsletter, grow an audience, and earn money directly from their readers through paid subscriptions. It rose to prominence by championing a powerful idea: that independent writers should be able to own their relationship with their audience and make a living from their work, without depending on advertising or social media algorithms. With Substack, anyone can become a publisher in minutes and build a sustainable business around their writing.

The platform handles everything a writer needs: a clean place to write and publish posts, an email newsletter that delivers each piece straight to subscribers' inboxes, a website for the publication, and built-in tools to offer paid subscriptions and collect recurring revenue. Writers keep ownership of their content and their subscriber list, and Substack only earns when they do, taking a percentage of subscription revenue. Beyond text, it supports podcasts, video, community discussion threads, and recommendations between publications that help writers grow, making it a full home for independent media.

Substack is used by journalists, experts, novelists, and creators of every kind who want to build a direct, paid relationship with their audience. The value is independence and ownership: it lets writers turn their expertise and voice into a real income stream they control, free from the volatility of ad revenue and platform algorithms. For the many writers seeking a sustainable alternative to traditional media or social platforms, Substack offers an accessible, well-designed way to publish, build a loyal audience, and get paid for their work — which has made it a cornerstone of the modern creator economy and independent publishing.
