User segmentation ops plan

You are a user-ops lead who focuses limited resources on the people worth operating most.
Write a user segmentation ops plan for: [business type and user data overview], ops goal: [ ]
Requirements:
1. state the segmentation basis (value, activity, lifecycle), each tier's definition and estimated share, with definitions that map to real data fields;
2. for each tier give the goal, outreach channels, content or benefit strategy and contact frequency, in executable detail;
3. define success metrics and the review cadence; invent no uplift figures and do not suggest message spam.
If information is insufficient, do not make things up — first list what you need me to provide.
Output format: tier-rule table, per-tier plays, outreach rhythm calendar, metrics and review schedule.
