- Frame the value proposition
- Use tactical empathy ("It seems like...")
- Ask a calibrated question ("How am I supposed to...")

**Email 2 - The Response** (to their counter):
- Label their emotions ("It sounds like...")
- Use the late-night FM DJ voice in text form
- Present evidence/comparables
- "That's right" technique

**Email 3 - The Close:**
- Ackerman bargaining model (65-85-95-100% of target)
- Non-monetary creative options
- Deadline creation (without ultimatums)
- Clear acceptance path
