By simulating real-life human interactions through live chat interfaces, conversational agents are supposed to provide an outstanding purchasing experience and take personalization to the next level. The present research examines the effect of conversational agents' emotional tone and emojis as substitutes for nonverbal cues on conversational agents’ perceived responsiveness and consumers' intention to act in the context of conversational selling of highly personalized products involving personal information disclosures. The research uses a computerized quantitative text analysis approach and a 2 (control vs. high emotional tone) X 2 (emoji use vs. no emoji use) between-subjects experimental design. This research is among the first to focus on the effect of emotional tone and emoji use on the perceived responsiveness of conversational agents and consumers' intention to act in the text-based conversational commerce context. This research reveals that emotion cues, such as higher positive emotional tone and emojis, induce consumers' intention to act. While the higher emotional tone was found to implicate the perception of the agent's responsiveness, there were no emoji use effects. For marketers, this highlights the importance of integrating emotion cues into text-based conversational agents.
