Infoga is a tool gathering email accounts information (ip, hostname, country,…) from a different public source (search engines, pgp key servers and shodan) and checks if emails were leaked using haveibeenpwned.com API. Is a really simple tool, but very effective for the early stages of a penetration test or just to know the visibility of your company on the Internet.
