Free Email Provider Checker

Find out whether an address uses a free mailbox provider, a disposable domain or a role account such as info@ or support@.

How it works

What it does

We compare the domain with curated lists of free providers and disposable domains, check the part before @ against common role names, and suggest a fix when the domain looks like a typo of a popular provider.

Limits

What it cannot tell you

  • The lists are curated subsets, not complete. A domain missing from them is not proof that it is a business or non-disposable domain.
  • It does not check that the mailbox exists. Use the email verifier for deliverability.
  • Runs in your browser; nothing you enter is sent anywhere.
