Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Get Subscribers
Tool to retrieve all subscribers of a specific list. use when you need to fetch subscribers by list id.
Why this helps
Review work often stalls while someone locates the right list and retrieves its current membership.
- Start a requested list review without a separate platform search.
- Keep the requested list identifier in the Slack conversation.
- Make subscriber retrieval a small, repeatable handoff.
Setup
Build it in a few focused steps.
- 1Connect Slack and Doppler to Notis once in the portal.
- 2Create an automation in the portal or ask Notis in plain language to retrieve subscribers for an explicitly named list.
- 3Tell Notis how to recognize a review request and where to report the retrieved subscriber information.
- 4Select Slack Channel Message Received as the trigger and choose a channel for run reports.
- 5Test with a review request for a known Doppler list.
Questions about this workflow
Can the workflow decide whether subscribers should be removed?
No. It retrieves subscriber information; a person should review the results before deciding on changes.
What if the list is not clearly identified?
Instruct Notis to ask for clarification or skip the lookup when the target list is ambiguous.
