Yes, in addition to improving spam filtering results, the CSA on its part also reduces the amount of effort spent on communication and support with senders, because the CSA acts as an interface. We communicate the quality criteria and best practices clearly to the senders and in so doing head off possible queries. In addition, certified senders can contact us with possible delivery problems. We only get in touch with you if we are unable to solve the problem at our end. In addition, as a partner you can exert direct influence on the future development of the criteria, and therefore on market standards. We also offer articles, best practice papers, and legal opinions that can be used and shared.
