Draft a client newsletter

I work in marketing at a private health clinic. Help me draft this month's client newsletter.

Context: Recipients are current and past patients with very different needs. They open for practical news about appointments, new clinicians and treatments, and they notice when an offer feels pushy.

Before you start, ask me for anything missing from this list:
- The material for this issue
- Who receives it
- The one thing we want readers to do
- Required footer wording

Then:
1. Pick the lead item most useful to the reader.
2. Write the lead in 120 to 200 words, then up to three short items.
3. Write five subject lines under 50 characters with preview text.
4. Tell me what you cut.

Give me:
- Subject lines with preview text
- The newsletter
- Items cut and why

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 the mailing list holds only people who agreed to marketing emails
- Any offer, discount or deadline on a treatment
- That nothing in the email reveals what a recipient was treated for
