Follow up after silence

I work in marketing at a private health clinic. Help me follow up with someone who went quiet.

Context: People go quiet because the pain eased, the cost worried them, they felt nervous or another clinic replied first. A second message can feel like pressure.

Before you start, ask me for anything missing from this list:
- The original enquiry and our reply
- How long ago
- Anything new that is useful to them

Then:
1. Give a reason for writing that helps them.
2. Ask one easy question.
3. Write a final note that closes the loop politely.

Give me:
- A first follow-up
- A final follow-up

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general health information only. Never write anything that reads as advice on a person's own condition, and never suggest a treatment is certain to work or free of risk.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our clinical lead or the registered manager who approves marketing should see:
- That we still have their agreement to be in touch
- Any offer or deadline used to prompt a reply
- What the subject line reveals about their enquiry
