Route certificate warnings to the channel that can act.
Use email for early renewal reminders, Slack for watched operational channels, and signed webhooks when expiry, validation, or certificate-change events should update internal systems.

Expiry, validation, and certificate-change events keep the route and delivery attempts attached to the hostname.

Slack warnings
Use Slack for watched operational channels that should see 7-day, 3-day, 1-day, expired, validation-failure, or review-worthy certificate-change events.
Explore Slack certificate alertsSigned webhooks
Use signed webhooks when certificate events should create tickets, update inventory, feed client reporting, or enter incident routing after the receiver verifies the signature.
Explore signed webhook alertsAlert routing
Route warnings by workspace, hostname, channel, and severity.
Alert routes show which events go to Slack, email, or signed webhooks before a missed warning becomes a second problem.
Routing decisions
Connect channels after deciding who owns the next action.
A certificate warning should include enough context to assign renewal, DNS, CDN, load balancer, or receiver cleanup work without rerunning every probe first.
