A school learning platform sent every message as an immediate alert. Urgent notices reached students quickly, but routine reminders interrupted study and made truly important messages harder to recognize. Turning off all alerts would have solved the interruption problem, yet it could also have hidden emergency changes. The design team instead separated messages by purpose. Emergency notices remained immediate, while routine updates were grouped into a summary that students could open at a chosen time. Students could also mark one routine category as temporarily important during a project week. The team measured both the number of interruptions and whether students noticed emergency changes. The new design did not remove guidance. It made the level of interruption match the importance of the message, preserving both attention and access to urgent information.
