Make changing follow-up signals easier to revisit
When a follow-up flag is removed, Notis can check Evenium contacts and report possible matches to clarify the next step.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Get Contacts
Tool to retrieve a list of contacts from evenium. use when you need to fetch and optionally filter organizer contacts.
Why this helps
Removing a follow-up marker may leave a loose end if nobody checks whether the right contact was found.
- Revisit contact context when a follow-up signal changes.
- Keep the relevant lookup visible for review.
- Reduce uncertainty about whether a contact step is complete.
Setup
Build it in a few focused steps.
- 1Connect Slack and Evenium to Notis once in the portal.
- 2Create an automation or ask Notis to retrieve Evenium contacts when a follow-up message loses its pushpin reaction.
- 3Select the Message Reaction Removed trigger and filter for the pushpin emoji if available.
- 4Choose the run-report channel and test by removing a pushpin from a real follow-up message.
Questions about this workflow
Does this know whether the follow-up is finished?
No. Reaction removal is only a cue; review the retrieved contacts and message context.
Can it restore the pushpin?
No. The Evenium action retrieves contacts and does not change Slack reactions.
