What type of communication is primarily involved in an asynchronous interaction?

Asynchronous interaction is characterized by communication where the participants do not have to be engaged at the same time. In this context, email communication is the type that best represents this format.

When using email, one party can send a message, and the other can respond at their convenience without needing to participate in the conversation in real-time. This flexibility is a key distinguishing feature of asynchronous communication. In contrast, live chat, voice calls, and to some extent, text messages, typically require participants to be present at the same time, which aligns more closely with synchronous communication. Therefore, email communication stands out as the most representative example of asynchronous interaction.
