Frequently asked questions

What is a free email provider?

A service where anyone can create an email address for free, such as Gmail, Yahoo Mail or Outlook.com. Addresses on these domains are personal, not tied to a company.

Why distinguish free from business email addresses?

B2B companies often only accept work addresses in demo or trial forms, score leads with a company domain higher, or route them to sales. A free-provider list makes that check simple.
