The following disclosure relates generally to techniques for generating useful content based on user interactions, such as by enabling users to submit questions to and otherwise interact with an answer-providing service. In some situations, one or more interfaces are provided to allow users to specify a variety of types of questions for the answer-providing service, such as via a GUI and/or using a messaging interface based on email or other types of electronic messages. When communications occur via electronic messages, the answer-providing service may in some situations generate and include unique tracking identifiers in electronic messages sent to users, so that the users can reply back to the messages in order to provide a command to the answer-providing service that includes a tracking identifier previously sent to the user and thus verify that the command is sent by someone with access to the electronic messages of the user. |
