Email address verification database is an essential process to help businesses keep their list of emails free from invalid, disposable and incorrect addresses. It’s considered best practice to perform email address validation regularly through an email verification tool or API, helping improve email deliverability by reducing hard bounces and spam complaints. This ensures that your business is sending communications and emails to valid, interested recipients, resulting in higher engagement and conversion rates.

How often you validate your email validation database list will depend on how large your list is, how old it is, and how many entry points your list has (email opt-in forms, additions from customer service reps or store staff, content and data collection tools etc). However, a good rule of thumb is to verify all of your lists at least once a year, and before a heavy send period like the fourth quarter holiday season.

Why Every Business Needs an Email Verification Database

When you perform an email list validation, it’s essential to know when to remove an address and how to do it. It’s crucial to remove Undeliverable, Disposable and Risky addresses from your lists, as mailing to them can damage your sender reputation and prevent future messages from getting through at all. It’s also important to remove duplicate addresses, which can cause subscribers to receive multiple copies of the same message.

Finally, it’s a good idea to add in real-time email validation at the point of collection, so that every new contact is verified before they get added to your list. This can be done by adding an email address checker to your web forms or physical collection processes. Kickbox, for example, offers a simple and easy-to-use email verification software that you can integrate with your ESP or marketing automation platform.
