The CSA is a network of email senders and recipients. Please feel free to contact the CSA if you are of the opinion that there is a lack of clarity concerning any legal or technical issues in the sending of emails. You can also make your own contribution if you are an expert in a particular field. If your company is a member of the DDV or the eco Association, further possibilities for participation exist. Simply contact us directly!

Yes, we even seek this out. Through the feedback, we can identify problematic senders or their customers and address the problem. This helps us to maintain the high quality of the Certified IP List. Ideally, this should be done via automatic reporting. We have identified several GDPR-compliant options which we can use for feedback. But a manual notification is also helpful.

Yes, as Mailbox and Spamfilter Provider you can test the CSA Certified IP list for improving inbound mail filters. Please contact us at info@certified-senders.org or use our contact form on our website to discuss the details.

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.

Yes, the use of the Certified IP List for incoming spam filtering is free of charge.

To become a CSA partner and use the Certified IP List, all you need to do is sign a license agreement. Through this agreement, we want to make sure that the Certified IP List is used properly, so that all parties involved derive maximum benefit from it. From a technical perspective, we make the Certified IP List available in various formats, such as xml or csv, so it can be integrated into spam filtering on your site as effortlessly as possible. Where required, take up individual contact with us and we can extend the formats offered.
