Is this free email domain real?

Some webmail domains raise the same question again and again. Each profile shows who runs the domain, whether it still issues new addresses, its mail servers and how it appears in our lists: ymail.com, mail.com, proton.me, me.com, email.com, outlook.com, aol.com, yahoo.fr, verizon.net and comcast.net. All ten are on the email domain profiles page.

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.
