Make a Slack reaction the signal for an approved campaign
When the agreed approval reaction lands on a campaign message, Notis can trigger its Customer.io broadcast without requiring a separate reminder to launch it.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Trigger Broadcast
Tool to manually trigger a broadcast. use when you need to override the default audience and provide personalization data after confirming the broadcast id.
Why this helps
Approval often arrives amid other messages, leaving someone to remember a second step in another tool.
- Let a visible approval signal initiate the next step.
- Avoid searching back through a thread to remember whether the campaign was approved.
- Keep the sign-off and campaign context together.
Setup
Build it in a few focused steps.
- 1Connect Slack and Customer.io to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally; state which approval reaction and approved broadcast should initiate the action.
- 3Choose Slack Message Reaction Added as the trigger, select a channel for run reports, and test with one real approval reaction.
Questions about this workflow
Can this distinguish an approval reaction from other reactions?
Describe the specific emoji and approval context in the automation instruction. Validate the behavior with a real example.
Does the reaction create or edit a campaign?
No. The available Customer.io action manually triggers a broadcast; it does not create or edit one.
