history

Project history and usage

nmail is a terminal email client for Linux and macOS by d99kris, with an interface intentionally reminiscent of Alpine but a smaller, simpler feature set. It speaks IMAP and SMTP, stores a local SQLite cache, supports optional AES-256 cache encryption, and includes setup paths for Gmail, iCloud, Outlook/Hotmail, and OAuth2 variants.

Project history

The public tag history starts with v0.99 on November 7, 2019 and continues through regular 5.x releases, including v5.13.7 on May 23, 2026. The README's out-of-scope list is useful history in miniature: nmail is not trying to be mutt, notmuch, or a multi-account mail workbench; it chooses one-account-per-session, remote IMAP/SMTP, an external editor, and a terminal UI.

Adoption history

nmail occupies the modern lightweight-TUI mail niche: easier setup than classic power-user clients, but still local and keyboard-first. Homebrew's API reported 54 installs in 30 days, 108 in 90 days, and 462 in 365 days when checked on July 1, 2026, with package-manager support also documented for MacPorts, Arch/AUR, and Guix.

How it is used

Users typically start with `nmail -s gmail`, `nmail -s gmail-oauth2`, `nmail -s icloud`, or `nmail -s outlook-oauth2`, then compose in `$EDITOR`, view through terminal/external viewers, search local cache, and optionally export cached mail as Maildir. Its privacy document states that it does not include telemetry or background network access beyond configured mail servers.

Timeline
