Monitoring spam rates on a per-user basis within a domain requires a comprehensive approach combining technical tools, policy implementation, and continuous monitoring. Due to the lack of direct per-user spam feedback from providers, alternative strategies are essential. These include leveraging platform-specific tools like Google Workspace Admin's Email Log Search and Microsoft Defender's Spoof intelligence, tracking negative engagement metrics (unsubscribes, complaints, low open rates), and analyzing DMARC reports to identify authentication failures. Setting up abuse aliases and feedback loops, while not always providing individual data, helps uncover problematic patterns. Regular manual audits, particularly within affiliate marketing, are critical. Implementing internal policies for CAN-SPAM compliance, training the sales team, educating users on avoiding spam triggers, and email warming-up are crucial preventative measures. If using a dedicated IP (Postmark) or Google Workspace, reputation and volume limits must be closely monitored. Since there's a lack of comprehensive dashboards, active enforcement and addressing repeat offenders is key. Finally it is useful to focus on negative metrics such as unsub rates, bounce rates and negative replies.

Monitoring spam rates on a per-user basis within a domain involves a multi-faceted approach. It encompasses tracking negative email metrics like unsubscribes and negative replies, leveraging DMARC reports to pinpoint authentication failures, and scrutinizing bounce and complaint rates provided by ESPs. Regular manual audits of email practices, coupled with monitoring engagement metrics and setting up feedback loops with ISPs, offer valuable insights. Proactive measures such as sales team training, user education on avoiding spam triggers, and email warming-up are also crucial for mitigating spam risks.

Monitoring spam rates on a per-user basis within a domain is challenging due to the limited data provided by email providers. While direct feedback loops for individual spam flags are unavailable, establishing an abuse alias, tracking unsubscribe numbers, and complying with GDPR and CAN-SPAM regulations are crucial. Internal monitoring to ensure CAN-SPAM compliance, especially within affiliate marketing programs, is essential. If using Google, tracking account shutdowns due to volume violations is recommended. Ultimately, addressing the root cause by enforcing policies and addressing repeat offenders is key, as simply moving to cousin domains is a common workaround for bad actors. Tools providing comprehensive dashboards for management are largely absent in the B2B spam space, emphasizing the importance of manual oversight and policy enforcement.
