result
The result field may contains three values: "bad", "ok", "unknown". The "ok" value means that the email successful passed through the SMTP check, DNS check, and this email address isn’t disposable. The "bad" value means that some of this checks were failed. The "unknown" value means that email hosting supports "catch all feature".
emailAddress
The email address which was verified.
formatCheck
Equal to "false" when the given email has incorrect format.
smtpCheck
Checks does the email address exist and can receive messages or not? The value will be null if the SMTP request could not be completed, mailbox verification is not supported on the target mailbox provider, or not applicable.
dnsCheck
Ensures that the domain name part in the email address, eg: gmail.com, can be resolved via DNS. This value will be "true" if the domain is 'good' and "false" otherwise. May be "null" for invalid or non-existing emails.
freeCheck

This value will be 'false' if the email is not disposable, and 'true' otherwise. May be 'null' for invalid or non-existing emails.
catchAllCheck
Tells you does this email address 'catch all' any emails for this domain or not. There is a special type of address that can receive email for any number of other addresses on the same host. This is common in businesses where if you send an email to support@example.com and another email to help@example.com, both of those emails will go into the same inbox. Possible values are 'true' or 'false'. May be 'null' for invalid or non-existing emails.
mxRecords
