Advanced tools
Email Inspector is a Node.js package for validating and inspecting email addresses.
You can install this package using npm:
npm install email-inspector
Here's how you can use Email Inspector in your Node.js application:
const emailInspector = require('email-inspector');
const email = 'user@example.com';
if (emailInspector.validate(email)) {
console.log('Email is valid');
} else {
console.log('Email is invalid');
}
Email Inspector is designed to verify email addresses against a curated list of free email providers. This validation ensures that your business communication remains uninterrupted and can operate smoothly.
You can customize the behavior of Email Inspector using the following options:
customFreeProviders (Array): An array of custom free email providers to consider during validation.
providersToRemove (Array): An array of email providers to exclude from the list of free providers during validation.
const emailInspector = require('email-inspector');
// Example 1: Basic validation
const isValid = emailInspector.validate('user@example.com');
console.log(isValid); // true
// Example 2: Custom free providers
const customProviders = ['customprovider.net'];
const isValidCustom = emailInspector.validate('user@customprovider.net', { customFreeProviders: customProviders });
console.log(isValidCustom); // false
