Notification kinds
Every notification says why you got it: the saved search, the deadline window or the data source behind it. The kinds are New matches (a saved search found a new notice), Deadlines (a tracked notice closes within 3 days, checked daily at 09:00 UTC), Awards ending (a recompete window alert, checked daily at 09:30 UTC), and Data sources.
Reading and clearing
Notifications (/vendor/notifications) groups unread and read items by kind. Mark one read, or read all of a kind. When nothing is left the page reads "You are caught up". The first time, before any alert exists, it reads "No notifications yet" with a Set up an alert link. Counts come from your newest 5,000 notifications.
The Team Inbox
Workspaces on the Team Inbox screen see alerts, deadlines, decisions waiting and team activity in one list, with a source rail for decisions, deadlines, alerts, compliance and activity. Clear with E, snooze with S (Tomorrow 8 AM, Monday 8 AM or Next week), open with O, undo with U.
Delivery
The Delivery panel lists channels: in-app is always on; email, Slack and Teams can be switched on or off. Slack and Teams take a pasted incoming-webhook URL. Email also needs your operator to have mail delivery switched on. Notifications are scoped to your company; a platform admin can delete one, nobody else can.
