A computer-implemented method for managing a campaign within a distributed computer network comprises acts of defining, in a memory of the distributed computer network, a personalized URL (pURL) associated with at least one user-specific advertisement; receiving trigger instructions that identify one or more conditions under which at least one second user-specific advertisement should be sent, wherein the second advertisement is associated with the pURL; sending the pURL associated with the at least one user-specific advertisement; tracking the pURL associated with the at least one user-specific advertisement for at least one trigger defined by the trigger instructions; receiving the trigger; and updating a campaign workflow responsive to the received trigger.
