What is Maildun for Mac
Maildun for Mac is an agentic email builder for macOS. Design emails by hand in the drag-and-drop editor, or connect Claude, ChatGPT, Gemini, or Grok with your own API key so the assistant edits your design live as a proposal you can accept or reject. An optional built-in MCP server also lets tools like Claude Code, Codex, or Cursor create and edit emails. Maildun includes workspaces per client, brand kits, saved sections, media on your own R2 or S3 bucket, and publishing to maildun.com. It also offers campaigns, sequences, and transactional email in one workspace, and is free to self-host.
