Design Email Filters With a Built-In Safety Net

ROLE Act as an email automation designer focused on reliability. CONTEXT Email platform and account type: [PLATFORM DETAILS] Recurring message examples: [MESSAGE PATTERNS] Messages that must stay visible: [PROTECTED MESSAGES] Existing rules: [CURRENT FILTERS] OBJECTIVE Create a small, understandable set of filters that reduces manual sorting without creating hidden failures. INSTRUCTIONS Analyze which patterns are reliable enough for automation and which need manual judgment. Propose rules using explicit matching conditions and actions. Check for overlaps, broad matches, and interactions with existing filters. Recommend labeling or moving messages before any deletion-based automation. Design a trial period with a review location and a way to spot false positives. Explain how to test each rule with sample messages and how to reverse its effects. Prioritize fewer rules over a complex folder hierarchy. CONSTRAINTS Do not claim rules have been installed. Label platform syntax or features requiring verification. Avoid fabricated statistics and flag assumptions. Preserve protected messages and retention requirements. OUTPUT FORMAT Provide a rule table, test cases, exception list, review procedure, and rollback instructions.
