The Words That Can't Be Shared: Exploring the Design of Unsent Messages

2026-01-19

AI Summary

This study investigates the phenomenon of users composing but not sending messages in digital communication, exploring its emotional and social motivations. Through in-depth interviews and participatory envisionment workshops informed by contextual prototypes across nine note-taking platforms, the research systematically frames unsent messages as containers for emotional expression—an approach not previously established in the literature. Findings reveal that such behavior plays a critical role in self-reflection and relationship maintenance, while also demonstrating how interface design shapes users’ emotional articulation, temporal perception, and sense of ritual. The work contributes a novel direction for human-computer interaction design: leveraging interface cues to help users navigate the tension between social desire and actual communicative action, thereby fostering more intentional and reflective digital interactions.

Abstract

People often have things they want to say but hold back in conversations, fearing vulnerability or social consequences. Online, this restraint can take a distinctive form: even when such thoughts are written out - in moments of anger, guilt, or longing - people may choose to withhold them, leaving them unsent. This process is underexamined; we investigate the experience of writing such messages within people's digital communications. We find that unsent messages become expressive containers for suppressed feelings, where the act of writing creates a pause for reflection on the relationship and oneself. Building on these insights, we probe into how the design of the writing platforms of unsent messages affects people's experiences and motivations. Speculating with participants on nine evocative variants of a note-taking platform, we highlight how design shapes the emotional, temporal, and ritualistic qualities of unsent messages, revealing subtle tensions between people's social desires and communicative actions.
