Email list verification isn’t just about crafting the perfect subject line or email copy, there’s a lot of background work that goes into building and maintaining a high-performing list. One of the most important is the use of email list verification to keep your lists clean and sane.

Email List Verification: The Importance of Verifying Your Email List

But what exactly is email validation? And how does it help you improve email deliverability, increase email engagement and save your business money? In this article, we’ll take a closer look at the what, why and how of email list verification so you can understand the value of cleaning up your data.

The most basic definition of email list verification is ensuring that the emails on your mailing list are linked to inboxes. It’s a process that checks each email address to make sure it has a local part, an at-symbol (@) and a domain name with an active MX record. It also ensures that the email is active and able to receive messages from your email provider.

Many businesses will perform some sort of email verification when they first collect an email address from a new subscriber, usually by sending them a code or link to click that confirms the inbox. This helps to ensure that you only add valid addresses to your list and that you can get the most out of your email campaigns.

However, this isn’t enough to ensure your email data is clean and healthy. It’s important to regularly perform an email verification check, as people change jobs, switch providers and even use disposable email addresses – all of which can lead to your emails landing in the spam folder.
