In their own words
Canary
Canary Mail is an email client for managing accounts you already have; it does not provide or host email accounts. It supports Gmail, Outlook, iCloud, Exchange, and IMAP accounts, with apps or access listed for Android, iOS, macOS, Windows, web, and extension platforms. A unified inbox, priority and unread views, selective notifications, snooze, pinning, and cleanup tools help organize messages. Growth and Pro+ include AI Copilot for drafting replies, suggesting subject lines, rewriting in a selected tone, summarizing threads, and searching across accounts. The maker says email is not used to train AI models and that triage and indexing run on the device. Asana and Todoist integrations can turn email into tasks. Pro+ adds PGP and SecureSend encryption, tracker blocking, and phishing detection. Free costs nothing; Growth costs $36 a year; Pro+ costs $100 a year. A seven-day trial needs no card and does not auto-bill; paid subscriptions are yearly, with lifetime purchases also available.
