Maildun for Mac is an agentic email builder for macOS. Design by hand in the drag-and-drop editor, or connect Claude, ChatGPT, Gemini or Grok with your own API key: the assistant edits your design live, as a proposal you accept or reject. Turn on the built-in MCP server and Claude Code, Codex or Cursor can create and edit emails too. Plus workspaces per client, brand kits with shadcn-style component styles, saved sections, media on your own R2 or S3 bucket, and publishing to maildun.com.

Tauri 2 let me build Maildun for Mac with the same React UI kit, theme tokens, fonts and icons as Maildun on the web, while shipping a native macOS app that uses the system WebView instead of bundling a whole browser. The native side handles what a web app can't: processing images on your Mac before upload and running a built-in MCP server with no Node.js needed.

Radix UIThe whole Maildun for Mac interface is built on shadcn/ui (the base-vega style on Base UI), so it looks and feels like Maildun on the web. Owning the component code made it easy to share one UI kit and one set of theme tokens across both. It shaped the product too: brand component styles work like shadcn/ui for email, with presets plus button style, shape and size you can tune.

Maildun for Mac uploads your email images to your own Cloudflare R2 bucket, from the Media page or straight from an image block, so they live in storage you own. R2's zero egress fees are a great fit for email, where images are loaded every time someone opens a campaign.

CursorClaude Code helped me build Maildun for Mac, from the Tauri 2 app and the React 19 editor to the AI assistant tools and the built-in MCP server. It works across the whole codebase instead of one file at a time, so I could hand it real features and review the changes. And it's one of the MCP clients you can design emails with in Maildun for Mac, so it's part of the product too.
