> Design product emails with a native Mac builder and an open-source platform

Maildun develops tools for designing and managing product email. Its Mac app is a native email builder in beta, combining a visual editing interface with an AI assistant and MCP support. Users can work with email content, brand settings, previews, and exported HTML as they prepare messages for their product or audience.

The wider project is an open-source email-marketing platform that can be self-hosted, with a managed version on a waiting list. That platform is being developed around campaigns, audiences, onboarding sequences, transactional messages, and shared workspaces. Maildun suits small product teams exploring a more directly controlled email workflow.
