Advanced tools
Cross-language temporary (disposable/throwaway) email detection library. Covers hundreds fake email providers.
The mailchecker npm package is used to validate email addresses and check if they belong to disposable email providers. This can be useful for preventing users from signing up with temporary email addresses that may be used for spam or fraudulent activities.

const email = 'example@example.com';
const isValid = mailchecker.isValid(email);
console.log(`Is the email valid? ${isValid}`);Check Disposable Email
This feature allows you to specifically check if an email address is from a disposable email provider. The `isDisposable` method returns a boolean indicating whether the email is disposable.
const mailchecker = require('mailchecker');
const email = 'example@disposable.com';
const isDisposable = mailchecker.isDisposable(email);
console.log(`Is the email disposable? ${isDisposable}`);The email-verifier package provides email verification and validation services. It checks the syntax, domain, and mailbox existence. Compared to mailchecker, it offers more comprehensive email validation features, including SMTP checks.
