Trigger
Channel Message Received

Why this helps
Manually copying a short attendee list into a separate name research tool adds friction to event planning.
- Process a short attendee list in one batch.
- Keep the results attached to the triggering Slack run.
- Reduce copy-and-paste during event coordination.
Setup
Build it in a few focused steps.
- 1Connect Slack and Genderize to Notis once in the portal.
- 2Create an automation in the portal or ask Notis in plain language.
- 3Write one instruction to detect an attendee list in a Slack channel message, extract up to 10 first names, request batch Genderize estimates, and mark them as unverified.
- 4Choose Channel Message Received as the trigger and select a channel for run reports.
- 5Test with a real attendee list you are allowed to process.
Questions about this workflow
Will it infer a person's identity from the estimate?
No. The estimate describes name-level statistical patterns only and must not be treated as a person's identity.
Can it handle long lists?
This workflow is scoped to a short list of up to 10 first names, matching the batch action's described use.
