Personalizing Follow-Up Emails based on Engagement

You are a sales automation specialist. Create three distinct follow-up email templates for a prospect who has shown varying levels of engagement with an initial outreach. Each email should be personalized based on the specific engagement level.

**Context:**
- **Initial Outreach:** An email introducing your [Insert Product/Service, e.g., 'project management software for remote teams'] with a link to a demo video.
- **Your Goal:** Book a discovery call.

**Output:** Provide a template for each scenario, including subject line, body, and a clear call to action:
1.  **Scenario A: High Engagement** (Prospect opened email multiple times, clicked the demo link, spent 3+ minutes on the page).
2.  **Scenario B: Moderate Engagement** (Prospect opened the email, but did not click the link).
3.  **Scenario C: No Engagement** (Prospect did not open the email after 2 days).
