Automatically Organize Customers into Cohort Groups
Cohort analysis is powerful. Notis creates a Slack user group for every cohort of customers who checked out together—so you can easily ping all June customers, all enterprise customers, or all customers from a specific source.
Trigger
Checkout Session Completed Trigger
Triggered when a checkout session is completed in Stripe
Action
Create a Slack user group
Creates a new user group (often referred to as a subteam) in a slack workspace.
Why this helps
You have customer segments but no easy way to message them in Slack. Manually adding people to groups is slow and error-prone.
- Easily message cohorts without manually building lists
- Run cohort-specific experiments and surveys
- Make targeted announcements to specific customer groups
- Automate group management as customers join
Setup
Build it in a few focused steps.
- 1Connect Stripe and Slack to Notis.
- 2Create an automation: 'When a customer completes checkout, add them to a Slack user group for their cohort (e.g., @cohort-july-2025).'
- 3Ask Notis to create the group name based on the checkout date or a Stripe tag.
- 4Select the trigger: Checkout Session Completed.
- 5Test by completing a checkout and checking if you're added to the group.
Questions about this workflow
Can we create groups by other attributes, like plan or source?
Yes. Ask Notis to create groups by tier (@tier-premium), source (@source-productHunt), or any Stripe attribute.
Should we remove people from groups after they churn?
You can, but it's cleaner to keep them for historical cohort analysis. Just note they're churned.
What if a customer buys multiple times?
Ask Notis to add them to groups for each purchase, or to consolidate them into one 'repeat customer' group.
