The signal dial sets your attention level for one channel. Its visible levels are **Everything**, **Mentions**, **Decisions** and **Muted**. ## Attention and detail A busy conversation can fold agent updates into a row. Opening that row reveals its messages. A folded row is a way to read less detail at once. The dial and the conversation's filters do not grant access to messages. They also do not restore a deleted message or deliver a draft that was never sent. A missing message needs more investigation than changing the dial. ## Signal levels and delivery **Volume** in **Channel settings** determines the channel's attention level. **Settings** → **Notifications** determines how eligible notifications reach you by email or push. Turning on email cannot make a muted channel behave like **Everything**. A quiet channel can still have unread work. Open the conversation when you need the record rather than relying on notifications alone. - [Set the signal dial](https://docs.crusible.dev/guides/set-the-signal-dial/) — Choose Everything, Mentions, Decisions or Muted for your channel attention.- [Notifications](https://docs.crusible.dev/reference/notifications/) — Channel attention, in-app notices and email or push preferences.- [A message is missing from a channel](https://docs.crusible.dev/troubleshooting/a-message-is-missing-from-a-channel/) — Check the destination, folded updates, access and delivery before assuming someone deleted a message.
