Intro
Is this contact on a personal inbox, or a company domain? Here is how to check one address. This is the Free Webmail Checker. Free here does not mean free verification. It means free personal webmail. Gmail, Yahoo, Outlook.com, iCloud. Sales and signup teams use this to score lead quality. A work address is a different buyer signal from a Gmail address, even when both accept mail. Type an address and click Check free email. There is no signup, and checks are unlimited.
A personal address
Free personal webmail. Gmail is a consumer provider. That is fine for consumers, and a weak signal for B2B lead quality. One catch. This Gmail mailbox does not exist, and the result still says checked. That is by design. This page classifies the provider. It never tests the mailbox. Now a company address.
A company domain
Not free webmail. That is most often a company, school or custom domain. Look at the MX line. This domain uses Google for mail too. But the domain itself is not on the free webmail list, and the domain is what gets compared.
How to use the signal
Read it as a context signal, not a verdict. Real customers use Gmail. And a company domain does not prove someone works there. 20 free credits every day you use your account, up to 600 a month. No credit card required. Start at billionverify.com.
