# MK-389 | Post-Purchase Usage Education Plan

For ordinary chat, upload `packs/mk-389.md`, which includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Post-delivery content matching the actual product**

Customer segmentation and actual eligibility to receive marketing messages are separate matters

## Required inputs

Provide: Member segment, actual purchased product, approved instructions/precautions and official product information, delivery date, contact eligibility and product cycle

## Method steps

1. Segment follow-up content for purchasers by status; the course materials pair purchased status with usage guidance + repeat purchase
2. Guidance must match the product actually purchased; do not send the same generic guide to every purchaser
3. The original course materials prescribe no fixed number of tutorial days or pieces; do not invent a schedule without product usage-cycle data

## Calculation and interpretation

Base repeat purchase reminders on purchase cycles and contact consent; this catalog does not actually send messages

## Required output fields

| Order | Field | How to fill it in |
|---:|---|---|
| 1 | Goal | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 2 | Audience | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 3 | Plan / task | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 4 | Evidence and assumptions | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 5 | Prerequisites | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 6 | Resources | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 7 | Deliverables and acceptance | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 8 | Unresolved items | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |

## Verification cases

**MK-389-A1 | Segment known, purchased product unknown**

Expected: Request product/instruction evidence rather than invent usage guidance
