Investigate Churn Before It Spreads

Unsubscribes happen, but you never dig into why. Notis creates a Slack channel for each one so you investigate immediately.

Trigger

Unsubscribe Trigger

Triggered when a subscriber unsubscribes from Mailchimp

Action

Create a channel-based conversation

Creates a new public or private slack channel with a unique name; the channel can be org-wide, or team-specific if `team id` is given (required if `org wide` is false or not provided).

Why this helps

Subscribers leave but you ignore the signals, repeating the same mistakes that drove them away.

  • Spot churn patterns quickly
  • Respond to feedback in real time
  • Prevent repeat retention mistakes

Setup

Build it in a few focused steps.

  • 1Ensure Mailchimp and Slack are connected in Notis
  • 2Tell Notis: 'Create a Slack channel when someone unsubscribes from Mailchimp so we can investigate'
  • 3Optional: include a channel naming pattern like 'churn-investigation-[date]'
  • 4Notis creates a new channel for each unsubscribe event
  • 5Manually post context (optional: Notis can pull feedback if available) and discuss in the channel

Questions about this workflow

Won't I get a lot of channels?

Yes, if you have significant churn. Consider filtering for high-value subscribers or batching investigations.

Can I see the unsubscribe reason?

If Mailchimp captures it, Notis can include it in the channel topic. Otherwise, add it manually when investigating.

Should I keep these channels long-term?

Archive them after a week of inactivity to keep your workspace clean. Set a reminder to review monthly patterns.
