How a Free Email Verifier Works
Email verification is the process of checking if an email address is functional to make sure that your marketing messages will reach their intended recipients. An email verifier can verify individual emails or entire lists of addresses. The best email verification tools are reliable enough to catch most invalid addresses while being easy-to-use for even inexperienced marketers.
Using a free email verifier can help you keep your mailing list clean and ensure that your campaigns are reaching the right people with the right message. It can also prevent bounces and spam reports that hurt your reputation with email service providers and make it harder to get your messages in the inbox.
Streamlining Your Email Marketing: How to Verify Email Addresses Online for Improved Campaign Performance
While the way an email verifier works may vary slightly, most of them run a series of checks to validate the validity of an email address. This starts with a syntax check that looks for the four components of a valid email: user name, address sign (@), (subdomain) and domain. It then pings the server to see if it is active and uses MX records to verify the domain.
Finally, email verifiers check for hard bounces and spam traps. This is important because if your campaign receives too many hard bounces and spam reports, the email service provider will start warning you and might eventually blacklist your address. An email verifier can prevent this from happening by removing invalid addresses from your list before your campaign is sent.
