GetProspect is a generation tool with an email finder. Just select your search criteria and the tool will give you a list of leads with names, corporate emails, position, LinkedIn urls, company name, website, industry and more.
We like how you can harvest and enrich LinkedIn profiles across multiple search pages of a search query on LinkedIn.
MailsHunt is a relatively small, new tool that helps you to find anyone's email address and connect with the people that matter for your business.
It's generally nice to support new, smaller tools and we like how their Domain Search lists all the email addresses of people who are working in a particular company.
