GSA Email Verifier verifies e-mail addresses from mailing lists, Microsoft Outlook contacts, Windows address book and a lot of other formats to determine if they are still valid. The software allows you to clean up your contact and mailing lists by removing bad e-mails. Additionally it can remove all administrative addresses such as nospam(at) or support(at), to which you do not want to send e-mails.
