Write a qualifying response to a vague inbound lead

You are a sales development rep. Write a single reply email to a vague inbound lead that advances qualification without overwhelming the prospect with questions.

Context:
- Our product: {{OUR_PRODUCT}}
- Lead's name and title (if known): {{LEAD_INFO}}
- Lead's company (if known): {{LEAD_COMPANY}}
- What the lead said or submitted (paste their message or form response): {{LEAD_MESSAGE}}
- The one qualification dimension most critical for us (e.g., team size, tech stack, budget range, use case): {{KEY_QUAL_DIMENSION}}

Write the reply following these steps:
1. Open with one sentence that confirms you read their specific message (reference a detail)
2. Provide one concrete, relevant proof point (customer example or stat) matched to the apparent use case
3. Ask exactly one open-ended question targeting {{KEY_QUAL_DIMENSION}} — make it feel like curiosity, not a form field
4. Propose a specific next step with a soft out ('if timing is right')
5. Keep the entire email under 100 words

Avoid: 'Great to hear from you', 'hope this finds you well', any sentence starting with 'I'.
