How to extract contacts from Whois

LetsExtract allows you to extract email addresses, phone numbers and addresses from a Whois database.

What is Whois?

Whois is a protocol that allows you to extract information about the owner of a domain. This information includes the domain owner's email address, contact phone number, address, the date when the domain was registered and the date the registration expires. The information can be stored both on a central server and directly on the server where the domain was registered.

How Whois Contact Extractor works

All you have to do is specify a list of domains to check. LetsExtract will send queries to the central server for a particular domain zone (.com, .org, .net, etc.). If there is no information on the central server, the program will address the server where the domain was registered. LetsExtract Email Studio will extract this information and display it on the Results tab.

Example of use

1. Run Whois Extractor and insert a list of domains to check:




2. After you click the "Start" button, LetsExtract begins its work of extracting email addresses and other information. You can track this process on the Queue tab and see the results on the Results tab:




3. Once the process is completed, you can process the list through the Results menu or save the results.


4. Since contact information is often protected by Private Person, we recommend using an email verification program to remove invalid or erroneous emails. Of course, you can use our Email Sender program if you need to start a mailing list.

Note: By default, LetsExtract only extracts email addresses. To enable phone number extraction click the Phone & IM Settings tab in the program's Settings window.
