disposable-email-domain

A large, auto-updated list of disposable / temporary / throwaway email domains (mailinator, 10minutemail, guerrillamail, …), with a tiny zero-dependency isDisposable() helper.

• 160,000+ domains, aggregated from 6 well-maintained public blocklists, deduped and normalized (lowercased, IDNA/punycode).
• refreshed weekly by a GitHub Action — a new version is published only when the set actually changes.
• Zero dependencies. Ships the raw list too, so you can use it however you like.

Install

npm install disposable-email-domain

Usage

import { isDisposable, domains } from "disposable-email-domain";

isDisposable("[email protected]"); // true
isDisposable("[email protected]");      // false
isDisposable("mailinator.com");         // true (bare domain also works)

domains.length; // 160000+  — the full array if you want it

CommonJS:

const { isDisposable } = require("disposable-email-domain");

isDisposable(input) accepts a full email (user@domain) or a bare domain, is case-insensitive, and returns boolean.

Why

Blocking disposable-email signups cuts fraud, fake accounts, and junk. Hand-maintaining such a list is a losing battle — this package keeps it fresh for you automatically.
