The Exclusion Calendar lets admins define specific dates when Matter should pause notifications and activity. This helps ensure messages and reminders are not sent on company holidays or other days when teams are offline.
Exclusion dates can be set at both the workspace level and the channel level. All exclusions are additive, meaning Matter will honor both workspace and channel exclusions together. Workspace-level exclusion dates apply to all channels. Channel-level exclusions apply specifically to the channel only.
What happens on exclusion dates
When a date is added to the Exclusion Calendar, Matter adjusts behavior as follows:
Celebrations: Celebrations are treated like a weekend and will be delivered based on your weekend delivery setting.
Feedback Friday: Skipped on exclusion dates.
Surveys: Applies to Pulse, Custom Surveys, and Onboarding Surveys.
These dates are treated like a weekend.Matter notifications and reminders: All Matter notifications and reminders are skipped on exclusion dates.
