Free email checker

Catch address mistakes and review the domain before you rely on an email address. Free basic checks, with no AI or paid verification service.

Check an email address for free

Check the format, public mail records, likely domain typos and a local disposable-email list. No account or API key needed. A mailbox can still be missing even when these checks pass.

AskQuokka checks this address on its server. Only the domain is queried through DNS; the mailbox name is not sent to an AI or verification provider. Addresses and results are not saved or included in analytics. No email is sent. DNS answers may be reused for up to one minute.

What does email verification mean?

Basic checks can catch a broken format, a likely typo, a domain that says it accepts no email, or a listed temporary-email service. A deeper mailbox check asks the receiving mail server about the particular address. This free checker performs the basic checks and keeps that individual mailbox unconfirmed.

AI can explain these signals, but it cannot reliably guess whether an inbox exists. Even a deeper check cannot guarantee that a future message will be delivered or land in the inbox.

Quoted and international mailbox names are marked as needing a specialist check. A domain missing MX records can still have a fallback mail route. Temporary DNS errors remain unavailable results rather than an invalid-address verdict.
