Proton Mail

Proton Mail is a secure email service that prioritizes user privacy through end-to-end encryption and a zero-access encryption model. Unlike mainstream email providers, Proton Mail does not scan email content for advertising purposes, ensuring that only users can view their emails.
The service is free and supported by paid subscriptions that offer additional features. Proton Mail includes various privacy tools, such as PhishGuard, password protection for emails, and options to hide real email addresses. The platform is open-source and independently audited, making it a trusted choice for individuals and businesses seeking secure communication.
Proton Mail is part of a broader suite of Proton services, including Proton Calendar, Proton Drive, Proton VPN, and Proton Pass, all designed to protect user data and ensure online privacy. The company facilitates easy migration from other email services and emphasizes its commitment to privacy laws in Switzerland.
