Email, distilled.
Introducing Box, a privacy-first desktop email client built exclusively for Linux. While other clients phone home, inject ads, or quietly let tracking pixels confirm you opened an email, Box does the opposite. It connects directly to your IMAP and SMTP servers, stores everything locally, and keeps your credentials locked in your OS keyring. No middleman, no cloud, no silent data collection. Tracking pixels are neutralized. Suspicious senders are flagged. Read receipts are silenced. Every message is verified for SPF, DKIM, and DMARC authentication so you know what’s real. Manage multiple accounts from a single window, search across all of them with blazing-fast full-text indexing, and keep working even when your connection drops. Verifiable zero telemetry, not just promised in a policy. Free forever with one account, or $10 once for unlimited. No subscription, no trial countdown, no crippled features, no catch. This is email the way it should have been all along.
