"After years of utilizing the CSA Monitoring Tool, I can confidently say that the latest release of the Certified Monitor is an invaluable asset. As an ESP, it provides comprehensive insights that enable us to investigate issues at their source and implement the necessary adjustments effectively. This tool has been instrumental in ensuring proper DKIM signing and maintaining compliance with Yahoo and Gmail's requirements. Additionally, its spam complaint monitoring feature has significantly helped us mitigate spam and fraud across our platform, streamlining our daily operations and enhancing overall efficiency."

"With the help of CSApi, the spam complaint rate and spam traps are loaded into the backend and dashboards are created with the help of Power BI. These are used to monitor deliverability and detect anomalies in order to target customers who have or could cause problems. As even the best of sender is seeing complaints and sometimes spam trap hits, it is less about the exact values and more about the trends and any sudden deviations from the standard. This saves us time in monitoring and we are happy with the external data we can easily use for that purpose!"

Jan Schapmans - Director Deliverability Services

"The data provided by the CSA offers our customers significant added value: we combine it with promio.connect data to generate unique KPIs that allow individual optimization of mailings in terms of maximum deliverability and optimal inbox placement. This data is made available in comprehensive dashboards. In addition, we use the data to trigger notifications when certain thresholds are exceeded and to control the permitted mailing volumes. A sender with poor complaint rates will automatically have their reach limited, protecting them and the promio.net infrastructure at the same time."
