Respond Fast to Churn Spikes

Unsubscribe rates spike and go unnoticed. Notis alerts you urgently so you can investigate before churn becomes a trend.

Trigger

Unsubscribe Trigger

Triggered when a subscriber unsubscribes from Mailchimp

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

A single bad email can trigger a wave of unsubscribes. By the time you notice, damage is done.

  • Respond before damage spreads
  • Investigate root cause quickly
  • Protect sender reputation

Setup

Build it in a few focused steps.

  • 1Ensure Mailchimp and Slack are connected to Notis
  • 2Ask Notis: 'Send me an urgent reminder in Slack if unsubscribe rate exceeds 1% in a single day'
  • 3Set your spike threshold (based on your normal rates)
  • 4Choose the channel for urgent alerts
  • 5Notis monitors unsubscribe events and alerts you if rates spike

Questions about this workflow

What is a normal spike threshold?

If your typical unsubscribe rate is 0.3%, alert at 1%. Adjust to your baseline.

What should I do when alerted?

Check your recent campaigns, read unsubscribe feedback, identify the problematic email, and consider a follow-up.

Can this be a false alarm?

Sometimes a popular email generates more unsubscribes. Setting smart thresholds prevents false alarms.
