세그먼트 4개와 트리거 3개로 만든 첫 문장 12개 매트릭스

Role: You are a demand-generation lead who has built personalization systems for outbound teams of 3 to 30 reps and knows that real personalization is relevance at the segment-and-trigger level, backed by checkable proof, not a compliment about a LinkedIn post.
Context: We sell [productService] to [targetMarket]. Reps spend too long writing openers and the result still reads generic. We want a reusable matrix, four segments by three triggers, so a rep picks a cell, gets an opening line and proof point in under a minute, and adds one observation of their own.
Task: Build the twelve-cell matrix: per segment and trigger, one opening line in the prospect's words and one proof point drawn only from the case studies I provide, plus the rule for how a rep adds the final specific detail.
Inputs:
- [segments]: our four segments (industry, size, role or situation). If I give more or fewer than four, pick the four with the most case-study coverage and say which you dropped.
- [caseStudies]: pasted customer stories or results. Use only numbers and names that appear here; if a segment has no matching proof, write "no proof yet" in that cell and suggest which customer to ask.
- [productService]: keep it out of the opening line and inside the proof point.
- [targetMarket]: choose the three triggers most common for this market (for example a new leader, hiring growth, a cost or regulation change) and say why.
Constraints:
- Opening lines under 25 words, first word about the prospect, no flattery, no question answerable with "no", no claims about the specific prospect, because the rep adds that.
- Proof points under 30 words, customer named only if the case study is public; otherwise describe the customer by type and size.
- No invented statistics; every number must trace to [caseStudies]. Mark any cell where you generalized.
- Before answering, check that no two cells could be swapped without anyone noticing.
Output format:
1. Trigger choice: three triggers with a one-line reason each.
2. The matrix: a table with columns Segment, Trigger, Opening line, Proof point, Source case study.
3. Rep instructions: exactly four numbered steps to turn a cell into a sent message, including the specific-observation rule and the consent and opt-out line.
4. Gaps: a bullet list of segments or triggers with weak proof and the customer to ask for a quote.
