Help page for Email Verifier


1. Check Connection Before Processing

Enable checking Internet connection (DNS servers, SMTP Port)  before processing.

2. Check for Updates

Enable checking for program updates online.

3. Skip Addresses from just blocked domains.

Program remembers mail servers which refused connection from your IP / email address and skip other addresses from this server.


When you send an email, the recipient's SMTP server asks for your domain name. It is recommended to use your real domain.
The use of somebody else's domain is allowed but not recommended - SMTP servers with advanced levels of security may refuse connection from you. The email address in the "MAIL FROM" line should be valid. If it is not valid, mail servers may refuse connection with you.



Press "Test" button to test current SMTP connection.

Connection Type:

  • Direct (TCP Port 25) - by default
  • Socks Proxy (4/4a/5)

Some of ISP are blocking the SMTP port (25), meaning that you can not contact a mail server and verify email address. In this case you have to use the external Socks Proxy Server. Configure Socks Proxy Server on "SOCKS Proxy" Page. We draw your attention that you should use just SOCKS (4/4a/5) proxy server, not HTTP proxy server, which is usually used in Internet Explorer.

In case of blocking, you also can connect through anonymous VPN server. You can read more and buy them here: www.findnot.com

Max Threads: 20.. 200

Depend on PC performance and internet connection speed.
Recommended values:
128  Kb/s: 20
256  Kb/s: 40
512  Kb/s: 100
1024 Kb/s: 200

Timeout: 30..120 seconds (default = 30 seconds)

You can raise this value only if you have "bad' Internet connection.

Threads per mail server:

Some SMTP servers detect multiply parallel connections from the same IP address and reject them. Raising this value will speed up processing, but you can get many false "Bad" results.

Domain Rules

Email Verifier Professional - Domain Rules

There are some SMTP servers configured to receive messages for not-existed accounts, so you cannot check emails from such domains.  So, to speed up the checking process (do not waste time for checking such email addresses because they will be marked as "Good" anyway), you can simply set the rule: all the email addresses for this domain are valid
