Make retention cohort requests easier to act on
A Slack DM can become a clear Aryn plan for a retention cohort question, ready for review.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Generate plan
Tool to generate a query plan without executing it. use when you need to review the logical plan before running your query (e.g., "generate a plan for revenue breakdown by region").
Why this helps
An important retention question can disappear into a private conversation before anyone defines the analysis.
- Preserve the question and its context.
- See the query logic before results are requested.
- Reduce the mental load of remembering follow-up.
Setup
Build it in a few focused steps.
- 1Connect Slack and Aryn to Notis once through the portal.
- 2Create an automation and name it for retention cohort requests.
- 3Write one plain-language instruction asking Aryn to plan retention cohort questions sent by Slack DM and return the plan.
- 4Choose Direct Message Received as the trigger and set a channel for run reports.
- 5Test with one real cohort question in a DM.
