A message originator may generate messaging data for selective communication by a messaging provider via an interface generated by a browser software application. The user may also interact with various content providers such that event data is generated based on the user interaction with each content provider. The messaging provider can then obtain the messaging data and the event data to determine a target set of messages to be published. Additionally, the messaging provider can select a set of message recipients to receive, or otherwise access, the target set of messages based on filtering criteria submitted by the message originator, content provider, service provider, and/or message recipients. Credit may be allocated based on activity associated with the communicated messages. The messaging provider may also facilitate additional interaction between the message originator and the message recipients including the initiation of additional communication channels.
