Prospect King makes it possible to find and verify email addresses, either in bulk or one by one. It lets you find emails for B2B prospects. You only need to identify a company, and the tool will do the work for you in terms of finding the email addresses of the prospects in that company. It allows you to generate leads through this means. Apart from B2B prospects, it can help you find email addresses for CEOs and directors among others for B2B prospecting companies. Email addresses verification is also possible with this tool, which allows you to do this in bulk using a CSV file.
