Overview

What is Proton Mail?

An inbox built around private custody

Proton Mail keeps its core infrastructure in Switzerland and limits the service's ability to read stored account data. Its web and mobile interfaces handle ordinary inbox work without making people manage PGP keys by hand. Free accounts suit light personal use. Mail Plus expands mailbox and address allowances; business plans bring user administration and organization controls. Paid bundles are also available for people using Proton's wider app suite.

Where it earns a place

Personal records: Keep financial notices, health correspondence, and account recovery mail in a privacy-first inbox.
Freelance identity: Use a branded address while keeping work separate from advertising-driven services.
Small teams: Use shared organizational controls when Google or Microsoft feels too data-hungry.
