Suppressed alerts in the inbox
Why some alerts show as "suppressed" in the Alerts Inbox — quiet hours, digest queueing, maintenance mode — and what each reason means.
Suppressed alerts in the inbox#
The Alerts Inbox shows every alert decision — including the ones we chose not to send. A row with status suppressed is an audit trail so you always know why something didn't reach your phone.
Reason labels#
| Reason key | What it means |
|---|---|
| Quiet hours active | Your quiet-hours window is currently in effect and the alert is non-critical. Will not be redelivered. |
| Queued for digest | Your alert frequency is hourly or daily; the alert is batched. Look at the scheduled-for column for the send time. |
| Maintenance mode | The site is in an active maintenance window — alerts during planned work are dropped on purpose. |
| Duplicate within window | An identical alert fired recently and was de-duplicated to avoid spam. |
| Channel disabled | The destination channel was disabled (e.g. broken webhook, revoked Slack URL). |
| Acknowledged elsewhere | A teammate already acked the parent incident, so this follow-up step was skipped. |
Reading a suppressed row#
Each row carries a small context payload with:
scheduled_for — when the alert *will* be sent if it was deferred (digest only)mode — hourly or daily, for digest rowsdigest — true if grouped into a batchWhat to do#
