What are requirements for maintaining certification?

Maintaining certification requires ongoing compliance with program standards. Typical requirements include: keeping complaint rates below thresholds (often under 0.1%), maintaining proper authentication, responding to abuse reports promptly, and passing periodic audits.

Monitoring is continuous. Programs track certified sender metrics and flag violations. Minor violations may trigger warnings; sustained violations lead to suspension or decertification. Re-certification after decertification requires demonstrating remediation.

Hidden requirements include: keeping contact information current, responding to program communications, updating authentication when infrastructure changes, and adapting to evolving program standards. Certification isn't set-and-forget; it requires ongoing attention.
