Design on-brand emails by hand, with AI, or over MCP
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.
