ProtonMail has long been seen as the standard-bearer for private email. Based in Switzerland and marketed as a secure alternative to mainstream providers, it has attracted users seeking protection from corporate and government surveillance. The service delivers strong encryption for email content, but closer examination reveals its privacy is limited and dependent on centralised systems.
While ProtonMail encrypts messages, subject lines remain visible and metadata such as sender addresses, timestamps, and routing information can be accessed. In 2021, the company admitted to logging IP addresses and cooperating with a government investigation, showing that Swiss jurisdiction is not an impenetrable shield. Emails are stored on ProtonMail servers, leaving them vulnerable to pressure, hacks, or shutdowns. For users expecting total control, these gaps are more than minor inconveniences—they expose the limits of centralised “privacy” solutions.
ProtonMail gives the impression of sovereignty without delivering it. Users do not fully control their data, identity, or legal context, leaving them dependent on the provider and its host country. It offers an improvement over traditional services, but not a fundamentally new approach to secure communication.
By contrast, decentralised email systems like DMAIL aim to remove these dependencies entirely. End-to-end encryption extends to subject lines and metadata, and messages are distributed across blockchain-based networks rather than stored in a single server location. Wallet-based identities give users full ownership of their accounts, while on-chain storage ensures messages cannot be altered or deleted without consent. This model shifts trust from a central authority to code, allowing users to maintain true privacy and control.
ProtonMail cannot surpass the structural limits of centralised Web2 systems. Real privacy, advocates argue, requires decentralisation, user sovereignty, and resilience to external pressures. As the digital world moves further into Web3, email and other communication tools may finally reflect the trustless, user-owned model already transforming finance and identity management.
