Best Alternatives to Maildun for Mac in 2025
Maildun for Mac is an agentic email builder that lets you design on-brand emails by hand, with AI, or over MCP. It offers a drag-and-drop editor, AI integration with popular models like Claude, ChatGPT, Gemini, and Grok using your own API key, and an optional MCP server for tools like Claude Code, Codex, or Cursor. With workspaces per client and a focus on live AI-assisted editing, Maildun is a unique tool for Mac users. However, if you're looking for alternatives—whether for cross-platform support, different AI integrations, or specific features—here are the best options to consider.

BEE Pro
BEE Pro is a collaborative email design tool with a drag-and-drop builder, AI writing assistant, and brand style guides. It allows real-time co-editing and integrates with various marketing tools.

Topol.io
Topol.io is a simple, web-based email editor with a drag-and-drop interface and AI-powered content suggestions. It's known for its ease of use and quick export to various platforms.

Knak is an enterprise email and landing page builder with a drag-and-drop editor, AI content generation, and strong brand governance. It integrates with major marketing clouds and offers approval workflows.

Postcards
Postcards is a web-based email builder with a drag-and-drop editor and AI-assisted design. It focuses on speed and simplicity, allowing quick creation of responsive emails. It lacks Maildun's agentic AI and MCP features, but it's a good alternative for those who want a straightforward, browser-based tool.
GrapesJS
GrapesJS is an open-source web builder framework that can be used for email design. It offers a drag-and-drop editor and can be extended with AI plugins. While it requires more technical setup and doesn't have Maildun's native Mac app or MCP server, it's a flexible, free alternative for developers who want full control.
While Maildun for Mac stands out with its agentic AI, MCP server, and native macOS experience, several alternatives cater to different needs. Stripo and BEE Pro offer robust web-based design with AI and collaboration. Chamaileon and Knak focus on brand consistency and enterprise governance. Topol.io and Postcards provide simple, quick email creation. GrapesJS is ideal for developers seeking an open-source solution.
