Feature Comparison Summary
Canary Mail folds encryption, an AI copilot, and a unified inbox into native apps for Mac, iOS, Windows, and Android. It shines for sensitive or multi-account email, but its best features sit behind paid tiers and there's no web client. Overall, it's a solid, recommendable pick if privacy and inbox control matter to you.
Proton Mail backs its privacy promises with real substance: end-to-end encryption on every plan, open-source apps that are independently audited, tracker blocking, and a one-click switch from Gmail. The trade-offs are thin free storage, a 25 MB attachment cap, and rates tied to yearly billing. Overall, it's a recommendable pick for anyone who wants private email without technical fuss.
Canary Mail is a cross-platform email client that replaces built-in mail apps with a security-focused feature set. It connects to Gmail, iCloud, Exchange, Office 365, and standard IMAP accounts, consolidating them into a single unified inbox. Its two defining capabilities are built-in end-to-end encryption and an AI assistant called Copilot that drafts and summarizes email directly inside the app.
Proton Mail is an encrypted email service from Switzerland and the world's largest end-to-end encrypted email provider. Over 100 million people and 100,000 businesses use it, including journalists and activists. Encryption runs quietly in the background, so no technical skill is needed. It fits everyday users who want to leave Gmail behind, professionals handling sensitive messages, and companies needing encrypted email with custom domains.
