Advanced Email Verifier 

Advanced Email Verifier can clean your list of email addresses by detecting invalid invalid IDs and domains. It can check every email address from a database or a mailing list and determine if the e-mails are still valid. This can protect your email server domain from getting blacklisted and increase your email campaigns' performance. Advanced Email Verifier can connect to any ODBC compatible database like MS Access, MS SQL, MYSQL, and Oracle to get your list of IDs.
