Email is the default channel, available on every plan. Each alert rule can route to one or more email addresses. Emails contain the diff payload (what changed, since when) and a link to the audit run. Daily and weekly digests are also available; configure cadence per recipient.
Slack
Slack alerts are a Pro+ feature. Connect via OAuth from the workspace integrations page; the bot is granted chat:write only and does not read message history. Each alert rule can route to one or more channels. The alert payload contains the regression diff and a link back to the run.
Microsoft Teams
Teams alerts are a Pro+ feature. Configure by adding an incoming webhook URL from a Teams channel into the integrations page. Wrendex sends a card with the regression summary and a link to the run.
PagerDuty
PagerDuty alerts are an Agency-tier feature. Configure by adding a service integration key. Wrendex maps severity to PagerDuty urgency: error -> high, warn -> low. Triggered events are de-duplicated by alert-rule + check + URL so the same regression does not page repeatedly.
