I need help with 3 questions !

1. Why would Teresa Carleo and Steve Martucci favor face-to-face communication over email when dealing with customers?
2. Why would Carleo and Martucci prefer to use electronic communication methods for certain types of communication within the company.
3. In the video, Carleo says that she worries that at times she communicates too much. What steps could she take to confirm that her messages are being heard and understood by others?

All are from Plant Fantasies.
