FMail2

The software provides a native macOS client that connects to Fastmail accounts, offering a desktop interface for sending, receiving, and managing email without using a web browser. It is built specifically for macOS, integrating with the operating system’s windowing and notification features to give Fastmail users a desktop‑focused experience.

Target users are individuals or organizations that rely on Fastmail for email and prefer a dedicated macOS application rather than a browser‑based interface. Because it is an unofficial client, it is not part of Fastmail’s official suite but serves as a third‑party alternative for macOS environments.

The current release is marked as discontinued; it no longer receives updates, security patches, or technical support. Users seeking an actively maintained version are directed to a newer build hosted at fmail3.appmac.fr.
