Apparatuses, systems, and processes are discussed for using metadata to take action on an SMS message on a proprietary system. In some embodiments, a wearable electronic device has a wearable device application that can present an SMS notification from an SMS application of a mobile computing device. The wearable device application can provide SMS notification data to a partner application of the mobile computing device. The partner application can perform a reverse look-up in a contacts application of the mobile computing device and construct a first contacts list with potential SMS-message senders. The wearable device application can present one or more SMS-message actions to a user of the wearable electronic device for a user selection thereof. The partner application can communicate with a partner server, which, in turn, can communicate with an SMS provider to effect the user selection of the one or more SMS-message actions.
