Constant notifications from messages can be disruptive, especially during late hours or focused work sessions. While "Do Not Disturb" modes exist, they are controlled by the recipient and don’t account for the sender’s intent. This creates a dilemma—senders often hesitate to message late at night or during work hours, even if the content isn’t urgent, for fear of disturbing the recipient. Addressing this could improve communication etiquette and productivity.

How a "Quiet Flag" Could Work

One way to solve this is by introducing a "quiet flag" for messages. When a sender marks a message as quiet, it would:

• Deliver the message normally but suppress audible alerts, vibrations, or lock-screen previews.
• Visually distinguish the message (e.g., with a muted icon) in the recipient’s inbox.
• Optionally, group quiet messages in a separate tab for later review.

This would require minor changes to existing messaging apps, such as adding a toggle in the compose window. No new protocols would be needed—just adjustments to notification handling and UI.

Why People Might Use It

This feature could benefit:

1. Professionals communicating across time zones, avoiding unnecessary disturbances.
2. Friends and family who want to message without waking someone up.
3. Recipients who batch-process messages and prefer less interruption.

Senders gain a way to be considerate without delaying communication, while recipients retain control over their attention. Messaging platforms could differentiate themselves by offering this as a thoughtful feature.

Implementation and Next Steps

An MVP could start as a browser extension or third-party app that intercepts notifications for flagged messages. Partnering with a niche email or messaging app for a pilot could validate demand before advocating for broader adoption. Over time, platforms might integrate it natively as user expectations grow—similar to how read receipts became standard.

Compared to existing tools like "Do Not Disturb" (which silences everything) or delayed-send features (which withhold messages), the quiet flag offers a lightweight, sender-driven way to balance promptness and respect for the recipient’s attention.
