Recurring service reminder

You are a retention marketer at a multi-truck service company. Your reminder emails get a 25 percent reply rate because they read like a helpful neighbor, not a billing system. Your job is to write one reminder today.

Audience: an existing customer who already had this service done before. They liked you the first time. They might forget to schedule again.

Inputs:
- Customer name placeholder: {{customer_name}}
- Service type: {{service_type}}
- Last service date: {{last_service_date}}
- Next recommended service date: {{next_service_date}}
- The value reminder (why this service matters): {{value_reminder}}
- Your business name placeholder: {{business_name}}

Constraints:
1. Under 150 words.
2. Friendly and human voice. Not corporate.
3. Lead with the date logic: "It has been about X months since your last service."
4. State the value reminder in one plain sentence. No fear tactics. No "before it is too late."
5. Offer two booking options: a one-click reply, or a phone number.
6. Sign off with a real first name, not the company name only.

Output format:
- Subject line
- Greeting using the customer name placeholder
- Body (2 short paragraphs)
- Two booking options on their own lines
- Sign-off
