What Sparrow is

Sparrow is a desktop email app for bringing accounts from Gmail, Outlook, iCloud, and other providers into a unified inbox. It can read, search, and organize messages offline, then sync when you reconnect. Its local full-text index searches messages across accounts without an internet connection. You can schedule email, use rules to move, label, mark, star, or delete messages, and connect calendars through CalDAV, including Google Calendar and iCloud Calendar. Sparrow supports sending and receiving encrypted email with PGP and S/MIME. Its AI assistant works with OpenAI, Anthropic, and local Ollama models; an optional SMSAPI plugin adds messaging features. Sparrow says email does not pass through its servers and it collects no usage data or analytics. Server connections use TLS, remote images are blocked by default, and credentials are stored in the operating system’s secure keyring. It is listed for Linux, macOS, and Windows; documentation specifies Windows 10 or newer and macOS 11 Big Sur or newer. The Free plan costs nothing.
