I also think that someone in Storybrooke knew of Bae's whereabouts other than August.

Maybe the Blue Fairy? could she have proctected her former self from the curse and sent Bae the postcard. She has both ties to August and Bae and could be the one giving them the information they needed back and forth. (like knowing Bae's name)
