Catch Churn Risk Signals Before They Become Cancellations
Churn rarely comes out of nowhere. Notis listens to churn signals from your analytics, support system, or product usage—and reminds your team to reach out before it's too late.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Churning customers send signals weeks before they leave (reduced usage, support complaints, payment issues), but nobody is watching. By the time you notice, they're already gone.
- Catch churn signals before they become cancellations
- Reach out proactively instead of reactively
- Reduce churn by 10-30% with early intervention
- Turn at-risk customers into loyal ones
Setup
Build it in a few focused steps.
- 1Set up a webhook in your analytics or CRM tool (Mixpanel, Segment, HubSpot, etc.) to send churn signals to Notis.
- 2Connect Slack to Notis.
- 3Create an automation: 'When a churn signal arrives, remind the team to reach out and understand what's wrong.'
- 4Choose the Slack channel where your customer success team works.
- 5Select the trigger: notis_webhook (incoming signals).
- 6Test by sending a test churn signal to the webhook.
Questions about this workflow
What counts as a churn signal?
Reduced usage, support complaints, failed payments, long gaps between logins, or custom rules you define in your analytics tool.
How quickly should we reach out?
Within 24 hours. The sooner you know about a signal, the better your chances of fixing it.
Should this automate outreach or just alert your team?
Start with alerts so your team can personalize the outreach. Over time, you can automate templated messages.
