What Is Email Validation?

Email validation is the process of taking an email address and making sure it’s “valid.” Usually, that means a combination of:

  • The email address is still active.
  • The email address is still receiving messages.
  • The email address belongs to a real person.
  • The email address belongs to the person you think it belongs to.

With the right email validation tools, you can upload your entire email list and automatically scan it for issues.

You’ll get a notification if an email address is no longer active, or if there’s a discrepancy between your records and what actually exists.

Why Use Email Validation Tools?

Most people use email address validation tools for one of two different purposes:

  • Cleaning an existing email list. First, you might be interested in “cleaning” an existing email list. Periodically cleaning this list of inactive or incorrect addresses can preserve the integrity of your campaigns.
  • Cleaning a new email list. Or maybe you want to verify the accuracy and integrity of a “new” email list. For example, if you’ve purchased a list of email addresses (largely considered a no-no in the email marketing world) or if you’ve followed our guide on how to build a targeted list of prospects, a cleaning step can ensure your data is as accurate as possible.

In either case, your goal is to make your email list as “clean” as possible.

Ultimately, your goals are to reduce bounces, reduce spam complaints, and prevent yourself from getting on an email blacklist.

Even if you have solid practices for collecting emails and managing your email lists, it’s still important to do rounds of email validation occasionally to scrub your list.

Like what you see from these email address validator tools?

Well, email validation is only part of the story.

If you want to maximize your chances of landing more sales and pave a path toward a more productive, successful sales team, you’ll also need a tool to help you measure and analyze your team’s email activity.
