Question: The app was checking a large eamil list (1'200 lines). I opened preferences and chaned from 10 to 25 threads and the app froze. I closed the window and opened a new one and restarted it and its working. My question is how many threads can I use. I have nothing else going on. I have a 12 core 2012 mac pro - 64 mb memory.

Answer: I usually recommend 5 or 10 threads. It is far enough for this purpose. Using more threads will not necessarily make the testing process faster, it can even cause problems or make it slower.

We are working on a 64-bit version of eMail Verifier with lots of optimizations. Maybe then you will be able to use more threads. The new version is still in development but I believe it will be ready for 2018 first quarter.

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).
