Email address verifier is a technology designed to identify whether an email address is valid or not without actually sending an email. Its benefits include ensuring that you’re mailing to reachable, real people, avoiding costly bounces and increasing the chances of your message getting delivered.

There are a few different ways to verify an email address, from basic syntax checks to sophisticated solutions that ping the address and check its MX record. Most of these tools are scalable to work on large lists and provide an instant score or status. However, there are some things that you should consider before choosing an email verifier tool.

Email Address Verifier: Why Verification is Key for Businesses

The first thing to consider is whether the email verification service is online or not. Online email validation is the best option because it doesn’t require any additional software or computer resources to use, is accessible anytime and anywhere, and does not rely on your IP for the verification process (which often causes problems).

Another important factor in choosing an email verification tool is its level of protection. Some online email verification services offer military-grade security to keep your data secure. ZeroBounce is one such email verification provider, and it’s used by some of the world’s biggest brands.

Email validation tools also allow you to check that catch-all emails are valid and able to receive messages. They can tell you if an email address is a role or alias, and they’ll also flag if the domain is fake or inactive.
