Verify email address free

There are several ways to verify an email address for free. Here are a few options:

1. Email Verification APIs: There are several free email verification APIs available that you can use to verify an email address. Some popular options include:
   • Mailgun's Email Verification API: This API allows you to verify an email address and check if it's valid or not.
   • EmailVerify: This API provides a simple way to verify an email address and check if it's valid or not.
   • Clearbit's Email Verification API: This API allows you to verify an email address and check if it's valid or not.
2. Online Email Verification Tools: There are several online email verification tools available that you can use to verify an email address for free. Some popular options include:
   • VerifyEmail: This tool allows you to enter an email address and check if it's valid or not.
   • EmailValidator: This tool provides a simple way to verify an email address and check if it's valid or not.
   • EmailChecker: This tool allows you to enter an email address and check if it's valid or not.
3. Regex Patterns: You can also use regular expression patterns to verify an email address. Here's an example of a simple regex pattern that you can use:

   ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$

   This pattern checks if the email address contains the following:

   • One or more alphanumeric characters, dots, underscores, percent signs, plus signs, or hyphens
   • An at symbol (@)
   • One or more alphanumeric characters, dots, or hyphens
   • A dot (.)
   • Two or more alphabetic characters

Keep in mind that this pattern is not foolproof and may not catch all invalid email addresses. It's always a good idea to use a more robust email verification method, such as an API or online tool, to ensure that the email address is valid.

Here's an example of how you can use this regex pattern in JavaScript:

function validateEmail(email) {
  const regex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
  return regex.test(email);
}

You can then call this function and pass in the email address you want to verify, like this:

const email = '[email protected]';
if (validateEmail(email)) {
  console.log('Email is valid');
} else {
  console.log('Email is invalid');
}
