Why this helps
Small follow-ups compete with bigger tasks and can vanish from memory before you get back to them.
- Turn a reaction into a clear request for a lookup.
- Reduce the need to remember a second manual search.
- Keep the result associated with the message that mattered.
Setup
Build it in a few focused steps.

- 2Create an automation and write one prompt explaining how to identify marked priority numbers.
- 3Pick Message Reaction Added and set an emoji filter if available.
- 4Choose a channel for run reports and test on a message with an E.164 number.
Questions about this workflow
Can this prioritize the number automatically?
The reaction can request a lookup. The listed Callerapi action retrieves information but does not assign priority or create tasks.
Can I choose a dedicated reaction?
Yes. The Slack trigger supports optional emoji filtering.
