Question: All emails return and say unable to verify. When I first purchased this product it worked fine, then it just suddenly quit working.
Answer: There are times when eMail Verifier is unable to test your e-mail addresses because of failure when trying to extract the DNS information. It is easy to recognize this problem. When eMail Verifier is unable to recover the server information for an address the 'Server' column displays 'Not found' in red rather than 'Found'.
In order to fix this issue just enter your DNS server address into the eMail Verifier preferences:
You can choose to use your system default DNS settings or your own. You can enter your internet provider DNS servers or any other available like Google's, OpenDNS's, etc. Here is a small list:
DNS Primary: 184.108.40.206
DNS Secondary: 220.127.116.11
DNS Primary: 18.104.22.168
DNS Secondary: 22.214.171.124
Comodo Secure DNS
DNS Primary: 126.96.36.199
DNS Secondary: 188.8.131.52
DNS Primary: 184.108.40.206
DNS Secondary: 220.127.116.11
Maintain clean mailing lists checking the validity of recipient's e-mails addresses. eMail Verifier can save time and money for businesses who send newsletters to their clients, nonprofit organizations who send bulletins to their members, or any person or business that needs to maintain a clean e-mail contact list.
eMail Verifier is your powerful solution for the standard "message delivery error." Email Verifier verifies every e-mail address from a given mailing list, allowing you to determine 80-90% of "dead" email addresses.
eMail Verifier works on the same algorithm as ISP mail systems do. Addresses for e-mail are extracted from a Domain Naming Server (DNS) and eMail Verifier tries to connect with SMTP-servers and simulates the sending of a message.
It does not send the message though - eMail Verifier disconnects as soon as the mail server informs the program whether the address exists or not. Email Verifier is a very effective piece of software that can verify over 10 e-mails per second .
It can verify single e-mails or huge lists. (eMail Verifier is multithreaded, providing high speed verifying).
