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.

What does the export look like: plain HTML I can send through any provider (I use Resend), or does sending go through maildun.com? And do dark-mode styles come out as their own block?
Congratulations on the launch, Dunn! 🎉 Ending the day at #9 is a great result. The detail I keep coming back to is the assistant editing your design live as a proposal you accept or reject — most AI email builders just overwrite what you had and you start over. Having the built-in MCP server so Claude Code or Cursor can create and edit emails too is the part I'd want to try first, since that's where my brand rules already live. Hope the day went well!
