An email verifier is an online service that allows you to check whether an email address or a database of addresses is valid and deliverable. It’s a tool that can help you maintain the integrity of your database, connect with customers, and improve performance metrics.
How it works
There are many different types of email verifiers available on the market, and some work best for you. You may need a single- or bulk-verification solution, a desktop tool, or a cloud-based service that you can access from anywhere in the world.
One of the most important features you should look for in an email verifier is a domain check. This check allows you to be sure that the domain name the email address is listed on is active, registered and working properly.

Another feature to look for is an MX record check. An MX record is the mail exchange entry that identifies the server responsible for accepting emails on behalf of the domain name.
The MX record check is an essential step for identifying garbage addresses, so make sure that the email verification service you choose supports it.
It also helps prevent you from sending emails to invalid email addresses, which can cause your email deliverability to plummet and, in turn, harm your sender reputation.
A good email verification tool will perform at least 7 steps of an email address validation process. Each of these steps will check the format and syntax of an email, as well as the MX record and the domain name. Some email verification services even go beyond this basic check and ping the email address with a server-response to confirm its existence.
