Different forms of completing a communication circle

In face-to-face communications, there are three ways to complete the communication circle:

1. Inquiry: You ask a question.
2. Responding with an answer.
3. Acknowledgement by saying 'thank you' or by nodding your head.

We do something similar with texting. Someone sends a text, the other person responds and then the first sender responds with a reaction button or by sending an emoji.

But emails can go back-and-forth for fear of seeming rude or unresponsive.
