Signal to providers:

• Recipients want this mail now
• Sender has improved practices
• Different behavior from crisis period

Cumulative effect:

• Takes weeks, not days
• Consistent positive signals required
• Single good campaigns not enough

What providers observe:

• Engagement rates improving
• Complaints decreasing
• Recipients interacting positively
• Sustained pattern change
• Consistent good behavior over time teaches new expectations.
