Email Count by Domain or Company

omnial/email-count

Given a domain (preferred) or a company name, returns how many email addresses are known for that organization -- split into personal vs. generic addresses, broken down by department, and broken down by seniority level. Returns only counts, never the addresses themselves, so it's a way to size a prospect list before requesting any of it.
