what is an email verification tool?

Email verification is a tool used to help companies validate and confirm the accuracy of contact information, such as email addresses, being submitted to an application or website. By verifying email address accuracy prior to an account or service being created, businesses can ensure that they're only dealing with legitimate users and that their contact database is consistently updated and contains accurate data.

The purpose of an email verification tool is to clean up contact lists and ensure that emails which are sent out arrive at the intended recipient's address. An email list may include addresses which are no longer valid due to either a user entering their information incorrectly or changing their address at some point in the past. A good email verification tool will identify such outdated emails and prevent them from clogging up the database and your employees' bandwidth.

When searching for an email verification tool, there are a few features you should look out for. Firstly, most tools offer primary checks which will check if an email follows general syntax requirements such as having valid characters in all positions. Additionally, more advanced options may include background checks which will determine if the domain is registered, check domain MX records or even assess if an account actually exists at that particular address. Advanced services can even offer further features such as checking message delivery rates in order to minimize bouncebacks and unsubscribe rates.
