Free Email validation API

Introduction

Email validation is essential for maintaining a clean and effective email marketing list. Invalid emails can hurt your sender reputation and waste resources. This guide explores how to use email validation APIs to improve your email deliverability.

Understanding Email Validation

Email validation goes beyond simple regex patterns. A comprehensive validation service checks multiple aspects of an email address to ensure it's valid and active.

Implementation Example

const validateEmail = async (email) => {
  const response = await fetch(
    `https://api.mailboxlayer.com/v1/check?${new URLSearchParams({
      access_key: 'YOUR_API_KEY',
      email: email,
    })}`
  );
  const data = await response.json();
  return data;
};
