Email addresses that don’t belong to real people are a huge problem for email marketers. They cost you money by not reaching your audience and causing hard bounces (delivery failures) that damage your sender score. The best way to avoid these problems is to use a genuine email checker to scan your list and remove invalid, high-risk emails before you hit send.

A genuine email checker also known as an email validator or verifier, is a tool that checks your marketing email lists to make sure the addresses exist and can accept messages from you. They’re used by companies of all sizes, from small startups to large enterprises and agencies. Most are free to try but require a paid subscription to verify more than a few addresses per month.

Genuine Email Checker: Best Tools to Ensure Validity

This free email verification service uses a variety of tests to check whether an email address is valid or not. It starts by checking whether the syntax is correct, such as the presence of the “@” symbol and proper placement of dots. Then it tries to connect to the mail server using SMTP and simulates sending a message to see if the mailbox exists and is active. It also checks for spam traps and disposable email addresses.

In addition to these basic checks, the tool provides a more detailed report categorizing each email address as valid, invalid or risky. This helps email marketers clean their mailing lists and improve email deliverability and engagement.
