Customer Churn Risk Alert

Every morning, this automation reads a Google Sheet of customer activity you already track (last login date, a usage score) and flags anyone who's gone quiet or whose usage has dropped below your threshold. Flagged customers trigger a Slack message and an email to the right account manager, and every alert is logged so you can spot churn trends over time.

Automation flow

How it works

  1. 1Every day at 08:00, the workflow reads your Customers sheet.
  2. 2Any customer who hasn't logged in for 14+ days, or whose usage score is below 30, is flagged.
  3. 3Flagged customers trigger a Slack message and an email — nothing is sent if no one is at risk that day.
  4. 4Every alert is logged to a Churn Alerts Log tab so you can see trends over time.
