Hi [Recipient's Name],

I wanted to share a success story from one of our clients, [Client's Name], who significantly enhanced their brand identity with a custom logo design from [Your Company]. You can read about their experience and see the logo [here/link].

I believe we could help your business achieve similar results with a unique and professional logo. Would you be interested in discussing this further?

Best regards,
