php wordpress – Subscribe to mailchimp and I can’t see it in mailchimp interface

I want to subscribe a user to mailchimp list like that:

 require_once( get_template_directory().'/inc/Mailchimp.php');
     $listId='********';
     $merge_vars=array(
         'FNAME' => $name
    );
    $apiKey='***********************';
    $mailChimp=new Mailchimp($apiKey);

    $result=$mailChimp->lists->subscribe($listId, array('email'=>$email),
            $merge_vars,false,true,true,false);

And I get a result from mailchimp:

[email] => aa@s.co
[euid] => *****
[leid] => *****

It looks like it is working and really sign this user, but when I get in to mailchimp the list is empty!

I tried to wait few days and see maybe it will update, but no…

Someone know why?
