How can I find a company's email address from their LinkedIn page?

Individuals and companies have profile on LinkedIn to connect with people for finding opportunities and business prospects. LinkedIn don't provide contact information for companies but there are some tools that extract companies information and find contact information based on extracted information. I know one tool "LinkedIn Company Extractor" and it works good to find email address and phone number from search engine and companies websites based on the extracted fields from LinkedIn.

"LinkedIn Company Extractor" is a desktop application to Extracts Company’s information Contact information (email, phone number available on google), Company Size, Followers, Website, Year founded, Industry, company type, Specialities, Address, postcode, and Country name etc. You can export your data in .xlsx, .csv,(opens in excel).

As an alternate you can find someone who is an employee of that company like CEO, Manager, etc. and by contacting that person you can get access to the company.
