## How It Works

1. **Research**: For each prospect, look up their role, company news, and pain points

3. **Send**: Dispatch with open/click tracking
4. **Follow Up**: Sequence of 2-3 follow-ups at configurable intervals
5. **Track**: Dashboard showing opens, replies, clicks, unsubscribes
6. **Optimize**: A/B test subject lines and track which performs better
