Questions about this workflow
Does the reaction itself prove consent?
No. The underlying message should contain explicit permission and an email; the reaction is only the processing cue.
Can I choose which reaction triggers it?
The Slack reaction trigger supports optional emoji filtering. Select the reaction that your team uses for approved signup records.
