Why this helps
An approval emoji can be hard to locate later when someone asks what was approved.
- Creates an email record tied to the approved message.
- Makes later decision checks less disruptive.
- Uses a deliberate signal instead of interpreting casual replies.
Setup
Build it in a few focused steps.
- 1Connect Slack and Agent mail to Notis once in the portal.
- 2Create an automation in the portal or by asking Notis in plain language.
- 3Ask Notis to email a record when the designated approval reaction is added, including the original message and channel context.
- 4Choose the Slack message reaction added trigger, apply the approval emoji filter if available, and choose a run-report channel.
- 5Test with one real approval reaction.
Questions about this workflow
Can the reaction alone establish what was approved?
The email should include the reacted-to message so the approval has context.
Can I use a different emoji?
Yes. Set the trigger's optional reaction filter and describe the chosen signal in the instruction.
