Abstract: Techniques are provided for secure and scalable electronic messaging. In one technique, a decision tree data and targeting criteria for a content delivery campaign are received and stored. Multiple entities that satisfy the targeting criteria are identified. First content from the decision tree data is retrieved and sent to a messaging account of each of the entities. The first content is presented in a message interface of a first entity. In response to detecting that the first entity has provided particular input, second content from the decision tree data is identified based on the particular input. First data associated with the particular input and the second content are presented in the messaging interface along with the first content.

Abstract: A method and system for dynamically re-allocating resources among multiple electronic content delivery channels is provided. The resources may be dedicated for a content targeting campaign that aims to persuade online users to perform a certain action. The content delivery channels provide targeted content to the online users based on the resources that are allocated to the channels. An effectiveness of each content delivery channel is measured. The measures of effectiveness may be used to determine whether and/or how much to a current allocation should be modified. Additionally, one or more rules that govern how to re-allocate resources may be enforced. For example, a rule may be that if a content delivery channel is not utilizing its allocation on a daily basis, then at least a portion of the unused portion is reallocated to another content delivery channel.
