    [_post_object:Leyka_Campaign:private] => WP_Post Object
        (
            [ID] => 690
            [post_author] => 3

            [campaign_template] => default

            [ignore_global_template] => 
            [is_finished] => 1
            [target_state] => no_target
            [target_reaching_mailout_sent] => 
            [target_reaching_mailout_errors] =>

            [count_submits] => 1
