LeadCrawler finds the email address of a website owner. Enter a website, and it returns the sites contact email. In my testing it finds 34% more emails than Hunter.io and more emails than every other tool I've tried.
LeadCrawler is a tool I've been developing on and off over the past several months, after being frustrated with other email-finding tools being overly expensive and not performing as well as they could. LeadCrawler can find thousands of emails all other tools miss. See https://leadcrawler.io/vs-hunter for a rundown on how it beats Hunter, for example.
This is NOT a tool for finding as many emails as possible all over the internet. LeadCrawler will only return 1 email per website you give it (the email of the site owner), and is designed for people who have a list of websites they would like to reach out to via email. It does not pick up any free emails like gmail or hotmail unless they definitely belong to the site owner.
