Embodiments provide systems and methods having an engine that gives stateless applications attributes of a ‘stateful’ process. To accomplish this end, a ‘snapshot’ of a transaction at a given point is taken and persisted until receiving confirmation that the transaction is completed. The snapshot may be a snapshot of data flowing in a stateless messaging system. The snapshot is maintained until confirmation that all intended recipients to which the transaction relates to have completed the steps they need to for the given transaction. The snapshot may be formed into a message and reflowed to an intended recipient to ensure that the recipient receives the message in the event that the initial delivery is unsuccessful.
