What kukudze does
You give kukudze an email address or a list. It checks each address and gives one result: Valid, Invalid, Risky or Unknown. You can filter the results and download them as a CSV file.
How the checks work
First we check that the address is written correctly. Then we check that its domain can receive email. Then we ask the mail server if it accepts the address. We stop before any message is sent. For addresses that pass, we also check if the domain accepts mail for any address, because then the mailbox cannot be confirmed.
What a result does not tell you
Valid means the mail server accepted the address when we asked. It does not guarantee that a message will reach the inbox.
