Written communication is best when you need to encourage interaction, express emotions, or monitor emotional responses.

Written communication is not always the best option when it comes to expressing emotions and encouraging interaction as it lacks the non-verbal cues that play a crucial role in conveying emotions and creating rapport. Face-to-face or virtual communication using video or audio is better suited for such purposes. However, written communication can be useful when monitoring emotional responses or ensuring a record of communication.

Written communication is not the best method when trying to encourage interaction or monitor emotional responses as it lacks the nonverbal cues and feedback that come with face-to-face or verbal communication. However, it can be useful for expressing emotions in a clear and organized manner.
