Email address validation is a technology process that helps you only send emails to legitimate email addresses. When you are equipped with a list of accurate and reliable emails, you will see more deliveries to inboxes, fewer bounced-back emails, and improvement in your reputation as an email sender.

Email has been a trusted communication tool for decades—and the channel has aged quite nicely. With billions of users per day (and still growing), email is a great way to connect with consumers on-the-go, at work, and even while watching TV.

According to Statista, the number of daily email users will reach 4.3 billion this year (2023) and continue to push on to around 4.6 billion by 2026. For marketing, sales, and departments everywhere, this means an even wider audience to connect and build relationships with.

A key challenge that many businesses can face is how they collect email (or any form of contact data) in the first place. They often have multiple, siloed databases that have little to no overarching governance around maintaining data quality.

Add to the mix manual data entry by employees or other people (which is prone to error) and there is bound to be incorrect or duplicate email addresses that comprise your CRM/ERP system. Once this filters through to your communications program, this can put you at risk of being an unreputable sender.

According to our research, up to 50 percent of data inaccuracies are due to human error. Think: Something as simple as a spelling error could be the reason you aren’t reaching contacts within your database, and worse, if you’ve procured your data from an unreliable source, your reduced sender reputation may result in being blacklisted. This is why you need email validation technology.

What is email validation?

Email validation is the process used to confirm the reachability and validity of an email address. It involves a rapid examination that identifies typos and missing structural elements of an email address (such as the @ symbol) that would act to the detriment of deliverability. Additionally, it verifies the association of a particular email address with a trustworthy domain and whether it’s a ‘disposable’ address.

Common use cases for email validation are:
  • Cleaning data prior to use in a marketing campaign
  • Verifying email addresses at the point of engagement – i.e. newsletter signup, purchasing transaction etc.
  • Maintaining an accurate customer database
  • Streamline your sales outreach

One point to note is the difference between consumer email data and business email data. Due to the way email validation works, it is far more effective on consumer email data than business email data, due to the latter being ring fenced by private security firewalls.

How does email validation work?

Whether you decide to integrate real-time quality control checks or clean your email list in bulk, Experian’s email verification software identifies errors within the format of the email address, and then pings the address to determine if it’s live and active. Ultimately, this ensures that if you send an email to this address, it will reach the right inbox.

  1. The user uploads a list of email addresses they would like to validate and the software runs a spell check on the email list, looking for missing punctuation or extra spaces. Anything that would invalidate the address
  2. Then, our technology filters out known spam traps from your email list. These are email addresses designed to catch businesses who are sending emails without permission. Filtering spam traps from your list allows you to avoid them at all costs and not be labelled as an untrustworthy sender.
  3. Lastly, we check the domains of your email list to make sure they are valid, and the email server is accepting mail.
