Automated Mixpanel Metric Drop Alerts
Every morning, WebRun opens Mixpanel, reads yesterday's volume for the events you care about, compares each against the same weekday last week, posts any sharp drop to Slack, and emails you a fuller breakdown when a metric falls far enough to look like a tracking break rather than normal movement.
How do I get alerted when a product metric suddenly drops?
WebRun opens Mixpanel every morning and compares yesterday's volume for your core events against the same weekday last week. Any sharp drop is posted to Slack with the percentage change and the segment behind it, and severe drops trigger an internal Gmail breakdown, so broken tracking is caught within a day.
- Broken event tracking is caught the next morning, not next month
- Drops are judged against the same weekday, so weekly cycles do not cause false alarms
- The team sees the affected segment before anyone opens a dashboard

Every action is checked against this policy before it runs.
Questions, answered
Will it email anyone outside the company?
No. The severe-drop email goes only to the internal address you set. Anything customer-facing is left for a human to write and send, and WebRun never emails a user or a partner on its own.
How does it tell a real drop from normal noise?
It compares yesterday against the same weekday last week and the trailing four-week average, so Monday is judged against Monday. You set the percentage that counts as a drop, and events falling to zero are always flagged.
Will it alert me every single morning?
Only when something moved. On a normal day it posts a one-line all-clear so you know the check ran, which keeps the channel quiet enough that a real alert stands out.
