Inbox Triage Taxonomy Builder

I receive {{email_volume}} emails per day from {{sender_types}} across {{tools_used}}. I need to respond to {{urgent_criteria}}, but also keep {{important_nourishing}}. My workflow: {{workflow_type}}. Create a triage taxonomy with:
1. 4-6 categories based on urgency/importance (not just folders)
2. Decision rules for each ("if X, then Y")
3. Response time SLAs per category
4. Automation rules I can set in {{email_platform}}
5. A weekly inbox review ritual (time + checklist)
Provide copy-paste filters, label structure, and a 1-page decision tree I can print.
