Few things are more useless and futile than having an email address on your website that no longer exists, and therefore all messages sent to it are not received by anyone, so it is always interesting to have a tool like GSA Email Verifier , which is responsible for checking, checking, verifying and determining if a list of emails is still valid (informing us which of these emails are no longer operational).
GSA Email Verifier allows the user to create their list of emails to check, but also to be able to import them from other formats (such as Outlook, TXT, CSV, XLS, etc.), as well as being able to export the result of verified emails to those formats.
GSA Email Verifier not only eliminates invalid emails, but all those that we have duplicates (and therefore repeated).
You can free download GSA Email Verifier 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
