Write rejection emails for: (1) A job candidate after a final-round interview who was strong but not selected. (2) A vendor whose proposal didn't meet requirements. (3) A customer requesting a feature you've decided not to build. Each should be respectful, specific about why (without being cruel), and leave the door open for future engagement. No generic templates — each must feel personal.
