Our verdict on Himalaya

Himalaya is an open-source, locally installed command-line email client from Pimalaya. It is designed for technical users who manage mail from a terminal and need flexibility across mail protocols, account configurations, and local storage formats. Shared commands cover mailboxes, envelopes, flags, messages, and attachments, while support spans Windows, macOS, and Linux. The product is distributed as a local binary or can be built from source, making it a desktop tool rather than a hosted web or mobile application.

Its main strength is protocol and ecosystem coverage. Himalaya supports IMAP and SMTP, along with ManageSieve and JMAP. It also connects with Gmail through the Gmail REST API and with Microsoft services through Microsoft Graph. For local workflows, it supports Maildir, m2dir, and pimdir. Multiple accounts can be managed through TOML configuration, while account-service discovery and a configuration wizard can help organize setup. TLS and HTTP/SOCKS5 proxy support add connectivity options for environments with specific network requirements.

Himalaya is free and open source, with no paid plan structure to compare. JSON output for command results makes it a practical fit for scripted workflows, automation, and users who prefer structured terminal output. The trade-off is equally clear: the product centers on command-line operation and local installation. Users seeking a graphical interface, hosted access, or a mobile application should choose a different email client. Himalaya is a strong match for protocol-flexible, terminal-based mail management, especially where local storage, multiple accounts, proxies, or machine-readable output matter.
