Proton Mail

Stop Using Insecure Email — Your Private Communications Deserve Military-Grade Encryption

Most email services treat your messages like postcards, readable by anyone who intercepts them. Proton Mail changes this entirely. Developed by former CERN scientists (the European Organization for Nuclear Research), this email application prioritizes end-to-end encryption so that only you and your recipient can read the contents. All servers are physically located in Switzerland, protected by the country's strict privacy laws — among the strongest in the world. This means no third parties, advertisers, or government agencies can access your data without your explicit consent.

Create a Secure Account in Under Two Minutes

Getting started requires only a few steps. Register a free account directly within the app — the entire process takes one to two minutes. During registration, you must choose a strong security key and provide a valid recovery email address. This security key is critical: if you forget it and need to use the recovery email, all existing messages and conversations in your inbox will be automatically locked. Therefore, treat this step with full attention. The app guides you through setting up two-factor authentication as an additional layer of protection.

No Ads, No Tracking — Only Pure Functionality

Proton Mail displays zero advertisements. Your inbox remains clutter-free, and your reading habits are never analyzed for ad targeting. The free tier includes 500 MB of storage, enough for hundreds of emails. For users requiring more capacity, the Turbo subscription removes storage limits and adds priority support. Every email, attachment, and contact is encrypted at rest and during transit using OpenPGP standards.

Full-Featured Email Client with Advanced Security Tools

The app includes all standard email functions: compose, reply, forward, search, folders, labels, filters, and auto-reply. Beyond these basics, Proton Mail offers password-protected emails — send messages that require a separate password to open, even if the recipient's email provider is compromised. Self-destructing messages automatically delete after a user-defined expiration time (from one hour to four weeks). All data remains encrypted on Swiss servers, and the app uses zero-access encryption, meaning Proton cannot read your emails even if compelled by law.

Two Paid Plans for Power Users

While the free version is functional, two subscription tiers expand capabilities significantly:

• Mail Plus (affordable): Unlocks up to 15 GB storage, custom email domains, 10 email aliases, and additional filters. Ideal for individuals needing more space and professional branding.
• Proton Unlimited (premium): Provides up to 50 GB storage, support for up to three custom domains, 15 email aliases, and access to Proton's entire suite (VPN, Calendar, Drive). Designed for professionals seeking a complete privacy ecosystem.

Both plans remove storage caps on attachments and offer priority customer support.

Customizable Interface and Privacy Controls

Navigate effortlessly through a clean, modern interface. The app supports dark mode, adjustable font sizes, and custom swipe gestures. Configure encryption settings per contact or globally. Enable automatic deletion of old messages after a set period. The settings menu allows granular control over notifications, signature, and folder organization. Every element is designed for maximum usability without sacrificing security.
