receiving a message from a queue, wherein the message is marked by a message flag being set, the message flag pertaining to a communication constraint that includes whether the message is eligible to be communicated through a relay server;

determining, based on the plurality of link-status flags, connections available to an interface circuit in the initiating communication device and the communication constraint associated with the message; and

providing transmission instructions to the interface circuit based on the available connections and the communication constraint, the interface circuit transmitting the message to the recipient communication device based on the transmission instructions, wherein, when the message is not eligible to be communicated through a cloud-based connection via the relay server, the message is transmitted to the recipient communication device using a different connection than via the relay server.

11. The non-transitory computer-readable storage medium of claim 10 , wherein the available connections include at least one of a Bluetooth connection with the recipient communication device, a Wi-Fi connection with the recipient communication device via an access point, or the cloud-based connection with the recipient communication device via the relay server.

12. The non-transitory computer-readable storage medium of claim 10 , wherein the operations further comprise, when there are currently no available connections and the message is eligible to be communicated through the relay server, establishing the cloud-based connection with the recipient communication device via the relay server.

13. The non-transitory computer-readable storage medium of claim 10 , wherein, when a Wi-Fi connection with the recipient communication device via an access point is available, a Bluetooth connection with the recipient communication device is unavailable, and the cloud-based connection to the recipient communication device via the relay server is unavailable, the message is transmitted using the Wi-Fi connection.
