Provided herein are systems, methods, and software for facilitating message sessions. In one implementation, a notification is received relating to a message submitted for delivery on behalf of a sender to a recipient. The message includes several components. At least one delivery policy is identified based on the content identified in at least one of the components. Delivery of the message is initiated according to the delivery policy.

Content based message delivery

Location inference using selected beacons. Data is received representing a set of beacons observed by a computing device. The beacons are located within a first geographic area. A subset (e.g., a clique) of the beacons is selected based on a coverage area of each of the beacons, where each of the beacons in the selected subset has a coverage area that overlaps with the coverage area of each of the other beacons in the selected subset. Using known or estimated positions of the beacons, a second geographic area is defined based on the selected subset of beacons and the beacon reference data and the coverage areas associated therewith. The second geographic area, smaller than the first geographic area, represents an approximate location of the computing device. In some embodiments, the computing device is calculated to be within the second geographic area with 95% probability.
