Keep the message proportionate
Use the shortest explanation that still tells the truth about the event, impact, and current position. For a message about how to limit contact to genuine emergencies, use this factual base: identify the content, account, place, person, channel, access, or behavior that must stop.
Give timing that can be trusted
Give a realistic date, a simple option, or a direct yes-or-no question and avoid vague promises such as soon. Give the required action, any lawful deadline, and the one permitted route for necessary matters. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Close the loop without drama
Do not debate the boundary repeatedly or threaten consequences you are not entitled to use. Save evidence, secure accounts, reduce access, and contact platform, workplace, legal, or emergency support when risk continues. A calm ending is more credible than a warning, a grand gesture, or language designed to provoke a response.
