DNS Live Check now includes an email verification tool. It is a quick starting point when an address looks wrong or a domain may be missing its mail settings.
Two checks, with separate answers
The tool first checks the address format. It then asks a public DNS resolver for the domain's MX and address records. A domain with mail servers, a domain that explicitly refuses mail and a domain whose DNS request failed should not receive the same result.
That distinction matters when you are helping someone fix a typo. A temporary network error is not a good reason to tell them that their email address is invalid. Likewise, finding an MX record is not enough to say that their inbox exists.
No test messages
This check does not send an email or open an SMTP connection. The address is submitted in a POST request rather than added to the page URL. The DNS cache stores results for the domain, not the mailbox name. Hosting or security services may have their own request logging.
What to do next
If the tool finds mail routing, use your normal confirmation-email process to check access to the inbox. If it finds no route, review the domain with MX Lookup. If the request fails, retry later.
For the details behind these results, read what an email address check can tell you. The aim is to make the next step clear without turning a limited DNS check into a delivery guarantee.
