Email marketing is a powerful tool for businesses of all sizes to reach out to potential customers, nurture leads, and drive sales. But, in order to make the most of this channel, you need to have a clean and accurate email list. This is where email validator tools come in. These tools help you to identify and remove invalid, duplicate, and non-existent email addresses from your list, ensuring that your messages are delivered to the right people and that you don't waste time and resources sending emails that will never be read. In this article, we will discuss the best email validator techniques in 2023 and how to pick the right tool for your business.

What is an Email Validator Tool and How Does it Work?

An email validator tool is a software program that checks the validity of email addresses by verifying that the email address is correctly formatted and that the email server is responsive. The tool typically checks for the following:

  • Syntax: The email address is in the correct format, such as ""
  • MX (Mail Exchange) records: The domain name of the email address is registered and has MX records, indicating that it is able to receive email.
  • SMTP(Simple Mail Transfer Protocol) server: The email server is responding and able to receive email.
  • Email address existence: The email address is actually in use and not a fake or non-existent address.

Once the tool has verified an email address, it will classify it as valid, invalid, or unverifiable. Valid email addresses are ones that meet all of the above criteria, invalid email addresses are ones that do not meet the criteria, and unverifiable email addresses are ones for which the tool cannot determine the validity.
