Sparrow

What Sparrow is

Sparrow is a desktop email app that brings Gmail, Outlook, iCloud, and other providers into a unified inbox. It can read, search, and organize mail offline, then synchronize after reconnecting. A local full-text index searches messages across accounts without an internet connection. Scheduled sending, calendar tools, and rules add workflow controls; rules can match sender, recipient, subject, or body and then move, label, mark, star, or delete messages. Sparrow supports encrypted email with PGP and S/MIME, connects calendars through CalDAV, and offers an optional SMSAPI plugin for texts, contact groups, templates, and history. Its AI assistant supports OpenAI, Anthropic, and local Ollama models. Sparrow says mail does not pass through its servers and that it collects no usage data or analytics. TLS protects server communication, remote images are blocked by default, and credentials use the operating system keyring. The Free plan costs nothing.
