[otrs] Bulk Customer Email

Hi I was wondering if there is a way of sending a bulk email to specifically selected tickets? We are planning create a new queue that is a beta request for software. However there will be people we do not wish to participate so we will select them and send a bulk email telling them that the have been unsuccessful. The present bulk action option would be great as we could tick the ones we don't want and send a note....however there is no option to send externally.....is this the case or am I missing something? Most of these people will not be logged as customers in the database. Cheers Jason
