Maily is an open-source WYSIWYG email editor built for developers, designed to produce rich-text emails that render reliably across major mail clients. Created in June 2023 by Bangladesh-based developer Arik Chakma and released under the MIT license, it ships as a React component built on Tiptap and shadcn/ui, and is widely paired with 📝Resend and React Email in the modern developer email stack.
The editor exposes a block-based authoring surface — text, images, buttons, dividers, columns, and variables — and emits HTML designed to survive the rendering quirks of Gmail, Outlook, and Apple Mail. With nearly 3,800 GitHub stars, Maily sits among the most-adopted open-source email editors aimed at the React ecosystem, alongside hosted competitors like Beefree, Stripo, and Unlayer that target marketers rather than engineers. The hosted playground at maily.to is free to try; the underlying packages can be embedded directly into any Next.js or React application. Chakma maintains the project alongside his role at roadmap.sh, and the project's positioning is engineer-first — drop the editor into your own send pipeline rather than adopt a separate marketing-email SaaS.
