Eppie review
An open-source desktop client for privacy-focused users who want encrypted email options.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Eppie is an open-source desktop email client from Tuvisoft OÜ, designed for privacy-focused users exploring encrypted and decentralized communication. It supports conventional email accounts through IMAP/SMTP, including Gmail and Microsoft Outlook, and can authenticate with Proton Mail. The stable desktop client is available for Windows, macOS, and Linux, while the product also includes PGP encryption, BIP39 seed-phrase-based local accounts, and encrypted local backups.
Its strongest distinction is the combination of familiar email access with locally controlled security features. Users can connect conventional providers while keeping local accounts based on BIP39 seed phrases and storing encrypted backups locally. Local AI agents are available for email processing, and the broader architecture includes decentralized storage and peer-to-peer email. This makes Eppie particularly relevant to users who value open-source software and want to explore email beyond a conventional provider-hosted model.
Eppie’s scope is narrower for users seeking a finished cross-device email service. Encrypted peer-to-peer messaging is described in testnet builds, and Android and iOS support remain work in progress. The published product focus is desktop, with conventional email functionality forming the stable foundation. Choose Eppie if open source, PGP, local account control, and decentralized communication matter more than a mature mobile experience. Users who primarily need established mobile apps or standard email workflows should consider a more conventional email client instead.
