- Numbers must come from [METRICS] or [TESTIMONIAL_NOTES] — never invented.
- The customer is the hero; [BUSINESS] is the guide. Check every paragraph for this.
- Write for [READER]'s concerns, not your product's features.
- Flag any gaps where you need more info from the customer before publishing.

BUSINESS='ShipRight Logistics', CUSTOMER_NAME='Bloom & Co.', CUSTOMER_DESCRIPTION='DTC candle brand, 50 employees', TESTIMONIAL_NOTES='shipping was chaos, 12% late rate → 99.2% on-time in 3 months; founder quote about sleeping again', METRICS='late rate 12% → 0.8%; shipping costs -18%; CS tickets -40%', GOAL='enterprise leads', READER='ops VPs at DTC brands'

How to use this prompt

Draft from notes, then send the customer the draft with the approval checklist — most approve in one round if you let them edit quotes. Publish with their logo for 3x the credibility.

Tips for the best results

The headline is a result, not a title: 'How X cut late shipments 93%' beats 'Bloom & Co. case study.'
Let the customer approve every number — one disputed stat kills the whole piece.
Repurpose: one case study = 5 social posts + 1 sales one-pager + 1 webinar.
