Send value checkbox in mail

i have a problem with send value multi checkbox by mail:

<input type="checkbox" name="wiztype[]" value="value1">
<input type="checkbox" name="wiztype[]" value="value2">
<input type="checkbox" name="wiztype[]" value="value3">
<input type="checkbox" name="wiztype[]" value="value4">
<input type="checkbox" name="wiztype[]" value="value5">

I'm trying to use the plugin for validating form, i have there:

var wiztype = $("input[name='wiztype[]']:checked").serializeArray();

In the mail-proces.php i have:

$wiztype = $_POST["wiztype"];

In the mail I have:

 [object Object],[object Object] (x number of selected boxes)

I tried to do foreach

if(!empty($_POST['wiztype'])) {
foreach($_POST['wiztype'] as $wiztypelist) {
        $wiztypelist;
}
}

What can i do with this? Please help :)
