I used a simplenews module to send user news, in user registeration I add field in user registeration refer to a A vocab ( list of some favorites)(as a name field_favourites) and user can select his favorite(s) from favorites category in registeration,
In Also in admin/structure/types/manage/simplenews/fields add that field again (field_favourites field that refer to favorites Vocab) .
The problem is when I create simplenews , and select one or some categories ,module email for all user not user that subscribe only for selected category(s),Where is the problem?
anybody know how can I achieve this job ? sending news only and only for user that subscribed for that category in user registeration ?
