How to extract email from websites online?

I have a list of about a million websites. How can I extract the bulk email address from their about or contact page automatically without writing the web scraping agent for each website? Let us see how we can scrape online emails in bulk through email extractor software.

Here is basic approach to extract email from website:

To extract email addresses, use this REGEX option with this expression: ([\w.-]+@(?=[a-z\d][^.]*\.)[a-z\d.-]*[^.])

This will find and scrape all valid emails on any website URL you crawl, here is my test on Rubular site - Rubular: (^[\w.-]+@(?=[a-z\d][^.]*\.)[a-z\d.-]*[^.]$) with this test string which extracted all 6 valid emails.

email@domain.com
my.email@domain.com
my_email@domain.com
first_middle_last@domain.com

If you want to send an email, please email us at info@domain.com
