Every workflow notification sends information to another place, so its destination is part of the data boundary. A shared channel, forwarded email, or phone lock screen may expose details beyond the people authorized in the original application.

Review recipients, queued reminders, membership changes, and device previews using synthetic examples. Keep destinations in controlled configuration rather than letting a model invent recipients. Add only the detail needed to prompt the next action. A secure delivery service cannot decide whether a particular person should receive a particular customer's information.
