Proton Mail

Overview

Proton Mail is a Swiss-based email service that prioritizes privacy and security by default. It uses end-to-end and zero-access encryption so only the sender and recipient can read message content — not even Proton can access it. Proton Mail blocks email trackers, offers password-protected messages, aliases, and advanced spam/phishing protection, and is available on web, desktop, Android, and iOS.
