history

Project history and usage

tmpmail is a POSIX sh command-line utility for creating and reading temporary email addresses from the terminal.

Project history

The official README describes tmpmail as a terminal temporary-email client that uses the 1secmail API to receive mail. It credits Mitch Weaver's 1secmail script as a major inspiration, placing tmpmail in the small-script tradition of wrapping web APIs for terminal use.

The project keeps the implementation deliberately portable: the README emphasizes POSIX sh and common command-line dependencies such as curl, jq, w3m, and xclip.

Adoption history

tmpmail's own README documents AUR, Pacstall, Nixpkgs, and Docker installation paths. The supplied source facts additionally list Homebrew, Alpine, and Nix package-manager entries.

This distribution pattern fits the tool's purpose: users often want a disposable inbox while testing signups, verification flows, or mail delivery from a terminal session, so package-manager availability is part of the value.

How it is used

The README documents generating a random or custom temporary address, listing an inbox, opening a message by numeric ID, viewing the most recent message, copying the address to the clipboard, listing available domains, and rendering HTML email through a terminal or graphical browser.

In the package-nerd niche, tmpmail is commonly useful as a throwaway CLI dependency in testing, demos, and local scripts where setting up a real mailbox would be heavier than the task deserves.

Why package nerds care

tmpmail matters because it packages disposable email as a normal Unix command. Its design favors shells, pipes, text browsers, and package managers over hosted dashboards.
