Correct a mistaken subscriber removal
A visible correction signal can help resolve an accidental removal without starting the handoff from scratch.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Add Subscriber
Tool to add a new subscriber to a specific list for a specified account.
Why this helps
Recovering from a mistaken list change can involve several steps and be easy to leave unfinished.
- Give a correction a clear follow-up path.
- Require an explicit contact, list, and subscription permission.
- Reduce the chance that a correction gets lost in the thread.
Setup
Build it in a few focused steps.
- 1Connect Slack and Doppler to Notis once in the portal.
- 2Create the automation in the portal or ask Notis in plain language to restore a mistakenly removed, opted-in contact.
- 3Specify the reaction-removal signal and require the message to name the subscriber, destination list, and consent.
- 4Select Message Reaction Removed as the trigger and choose a channel for run reports.
- 5Test with one correction example and confirm the subscriber is added to the intended list.
Questions about this workflow
Does removing any reaction add a subscriber?
No. The instruction should act only on the designated correction signal and a message with clear subscriber details and consent.
Can this restore someone who unsubscribed?
Do not use it to override an unsubscribe. Require clear, current permission before any re-addition.
