What each one is

The product in its own terms, so the numbers below have context.

Canary Mail

Canary Mail is an email client that consolidates multiple email accounts (Gmail, Outlook, iCloud, Exchange, IMAP) into a single unified inbox across desktop and mobile devices. It emphasizes end-to-end encryption, tracker blocking, phishing protection, and optional AI features for summarization and email organization, while maintaining a privacy-first architecture where emails remain stored with the user's provider.
