Checking a well-formed address
[email protected] typed into the email box
Format valid. The domain has mail servers listed in its MX records. No disposable domain was matched.
The check cannot confirm that the mailbox exists, because only the receiving mail service knows that.
Address with no mail domain
[email protected] typed into the email box
Format valid, but the domain has no mail servers, so mail sent to it is unlikely to arrive.
A domain without MX records cannot receive mail, so ask the person to check the address before accepting it.
Informazioni su Email Address Validator
An email validator checks whether an address looks right and whether its domain can receive mail. The tool first tests the format, including the part before the @ sign, the domain and the ending. It then looks up the mail servers published for the domain and shows them, so you can spot typing mistakes and dead domains before sending anything.
No message is sent to the address, and the tool cannot confirm that a particular mailbox exists, because only the receiving mail service knows that. A result of looks valid means the address is well formed and the domain accepts mail. Risky means the domain exists but publishes no mail servers, and not valid means something is wrong.

Domande frequenti
How does an email validator work?
It checks that the address follows the standard format, with one @ sign, allowed characters and a properly formed domain. It then asks the internet which mail servers accept email for that domain. If servers are listed, the domain is able to receive mail.
Does this prove the mailbox exists?
No. Only the receiving mail service knows whether a specific mailbox exists, and it does not share that publicly. This tool confirms the format and that the domain takes email. The only way to be sure an address works is to send a message and see whether it is received.
Is an email sent during the check?
No. The tool never contacts the mail server for the address and never sends any message. It only looks up public records for the domain, so the owner of the address is not notified in any way.
What does risky mean?
Risky means the domain exists but publishes no mail server records. Some domains can still accept mail in that situation, but it is unusual and often points to a typing mistake or an unfinished set-up. Double check the spelling of the domain before relying on it.
Why is a role address such as info flagged?
Addresses like info, sales or admin often go to a shared mailbox read by several people. They are perfectly valid, so the result is not changed, but a note is added in case you expected an address that belongs to one person.
