Form Maker e-mail verification

I am very happy with this plugin and have enabled e-mail verification. I can send and receive e-mail verification e-mails. But where is the verification information stored? Where do I see if a mail address is verified? Currently, all users of the form end up in the database.

The help page says ‘Activate this option, in case you would like the users to verify their email addresses. If it’s enabled, the user email will contain a verification link. Clicking on this link set the user email address as verified.
