Customer Advocacy Program Launch Email

As VP Customer Success, I am launching our customer advocacy program and need to invite our best customers.

Program Details:
- Program Name: {{program_name}}
- Key Benefits: {{benefits}}
- Commitment Level: {{time_commitment}}

Recipient Context:
- Customer Name: {{customer_name}}
- Their Success Story: {{success_highlights}}

Write a personalized invitation email that:

1. Opens with genuine appreciation for their partnership
2. Highlights their specific achievements with our platform
3. Introduces the advocacy program naturally
4. Explains member benefits clearly:
   - Exclusive access to product roadmap
   - Direct line to leadership
   - Networking with peers
   - Recognition opportunities
5. Addresses the time commitment honestly
6. Provides a clear next step

Tone should be warm, exclusive, and value-focused. Make them feel specially selected rather than mass-invited.
