Every rule has a routing block: pick channels, set quiet hours, dedupe windows, and escalation paths so noisy rules never wake the wrong person.
Quick answer
Inside each rule, open Routing to pick channels (email, Slack, webhook, SMS), set Quiet hours, choose a Dedupe window (default 15 min), and add an Escalation step if the alert is not acknowledged.
Routing options
Channels — one or many; overrides global defaults for this rule
Quiet hours — timezone-aware; alerts queue and fire when quiet ends
Dedupe window — suppresses identical fires within N minutes
Escalation — re-fire to a secondary channel after X min unacked
Auto-resolve notice — send a "recovered" ping when the condition clears
