What's changed? * Contacts that had **DND switched ON** previously - The system will continue to respect their wishes * Contacts that did **Not** have DND switched on previously, the system will continue as before  **DND Statuses** * **DND ‘On’** \- now means NO automated/ manual outbound messages are permitted to go out (previously, we let people send outbound messages manually and only restricted ‘Automated’ messages) * **DND ‘Off’** - all automated/manual messages continue to work as usual * **DND ‘Partial’** - Some Channels are unavailable for Outbound messaging (THIS IS NEW!) ![Step 1 screenshot](https://coreware-screenshots.s3.amazonaws.com/coreILLA_-_Smart_Lists_-_DoNotDisturb_(DND_Split)_1.png) 2.
