In today's digital age, email validation is a crucial part of building robust and secure applications. Whether you are managing user sign-ups, sending important notifications, or processing contact forms, ensuring that email addresses are valid and reachable is essential. In this comprehensive guide, we will explore the world of email validation using Kogger, a powerful logging and validation library. I will provide expert insights, practical examples, and answers to common questions, empowering you to master email validation in your applications effectively.

The Importance of Email Validation

Email validation is more than just checking if an email address has the right format. It plays a significant role in your application's functionality and security:

User Experience: Validating email addresses during registration ensures that users provide accurate contact information, reducing errors and enhancing user experience.

Data Accuracy: Accurate email addresses are essential for sending critical notifications, marketing messages, and maintaining a clean database.

Security: Validating email addresses can help prevent spam registrations and protect your application from malicious users.

Reputation: Sending emails to invalid addresses can harm your email sender reputation, affecting deliverability rates.

kogger.verifyEmail(email, (result) => {
  if (result.isValid) {
    console.log('Email is valid.');
  } else {
    console.log('Email is not valid.');
  }

  if (result.isReachable) {
    console.log('Email is reachable.');
  } else {
    console.log('Email is not reachable.');
  }

  if (result.isActive) {
