DND (Do Not Disturb) — stops everything outbound
DND is a flag you set manually on a contact record. When enabled, it stops ALL outbound communication from RootLogic to that person: automated texts, automated emails, manual texts, and manual emails. They can still call you. Use DND when a patient asks to be left alone entirely, or when you've confirmed a contact is not a real lead and want to halt automation before cleaning up the record.
