The README says it uses the mail.tm API, copies generated addresses to the clipboard, can fetch messages, show account details, and delete the temporary account. ### Project history The public GitHub repository was created in March 2022. Official release metadata available through GitHub begins with the 3.0.x series in September 2022 and continues through a 5.0.0 release in May 2024. The project remained focused on a narrow terminal workflow rather than becoming a full email client: generate an address with `mailsy g`, fetch mail with `mailsy m`, inspect account details with `mailsy me`, and dispose of the account with `mailsy d`. ### Adoption history Mailsy's README documents npm global installation and Homebrew installation for macOS users, and links Alfred and Raycast extensions. The input package-manager facts confirm Homebrew and Nix availability. Repository metadata shows several hundred GitHub stars, indicating modest but real uptake among developers who need throwaway inboxes for tests, signups, or quick verification flows. ### How it is used Typical usage is interactive and clipboard-oriented: run the CLI to create a disposable address, use it wherever a throwaway inbox is needed, then select messages from a terminal prompt and open them in the default browser. Deleting the account rotates to a new address. For package users, Mailsy is useful because it wraps the mail.tm disposable-mail workflow in a short command with no local service to run. It is best understood as a convenience CLI rather than infrastructure. ### Why package nerds care Mailsy is a small example of the modern npm-to-Homebrew pipeline for developer conveniences: a global Node CLI gains enough utility to appear in system package managers, even though the project itself is intentionally tiny. Its importance is practical rather than architectural: it gives shell users a quick disposable inbox without building their own API wrapper or leaving the terminal. ### Timeline - 2022: Public GitHub repository created. - 2022: GitHub release metadata shows 3.0.x releases. - 2023: 4.0.x releases published. - 2024: 5.0.0 release published. ### Related projects - The README says Mailsy uses the mail.tm API. - The README links companion Alfred and Raycast extensions for the same disposable-email workflow. ### Sources - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mailsy - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - mailsy: normalized package name match | nixpkgs package indexes: pkgs/by-name/ma/mailsy/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [notmuch](https://www.automicvault.com/pkg/brew/notmuch/) - Shares av.db curated category or tags: cli, developer-tools, email. - [notmuch-mutt](https://www.automicvault.com/pkg/brew/notmuch-mutt/) - Shares av.db curated category or tags: cli, developer-tools, email. - [mailpit](https://www.automicvault.com/pkg/brew/mailpit/) - Shares av.db curated category or tags: cli, developer-tools, email. - [action-docs](https://www.automicvault.com/pkg/brew/action-docs/) - Shares av.db curated category or tags: cli, developer-tools, nodejs. - [b4](https://www.automicvault.com/pkg/brew/b4/) - Shares av.db curated category or tags: cli, developer-tools, email. - [chalk-cli](https://www.automicvault.com/pkg/brew/chalk-cli/) - Shares av.db curated category or tags: cli, developer-tools, nodejs. - [corepack](https://www.automicvault.com/pkg/brew/corepack/) - Shares av.db curated category or tags: cli, developer-tools, nodejs. - [czg](https://www.automicvault.com/pkg/brew/czg/) - Shares av.db curated category or tags: cli, developer-tools, nodejs. - [generate-json-schema](https://www.automicvault.com/pkg/brew/generate-json-schema/) - Both packages touch the same language runtime or ecosystem.
