Reactions Drive Your Label System
You use reactions in Slack to flag, approve, or mark items. When you remove a reaction, that signal should disappear from Gmail too. Notis keeps your labels in sync.
Trigger
Message Reaction Removed
Triggers when a reaction is removed from a message.
Action
Modify email labels
Adds or removes labels on an email message.
Why this helps
You react to Slack messages to organize them, but removing reactions doesn't clean up Gmail labels. Your email stays cluttered with stale tags.
- Keep Gmail labels up-to-date with your real-time priorities
- Use reactions as a living organizational system
- Reduce clutter from outdated tags
- Lower cognitive load by having one source of truth
Setup
Build it in a few focused steps.
- 1Connect Slack and Gmail.
- 2Create an automation: 'When I remove a reaction from a Slack message, remove the matching label from Gmail.'
- 3Notis will use Message Reaction Removed as your trigger.
- 4Map which reactions remove which labels (reverse of your 'reaction added' automation).
- 5Test by removing a reaction from a Slack message and check Gmail.
Questions about this workflow
Should I set up both 'add' and 'remove' automations?
It's ideal to have both so your Gmail labels stay in sync with your current Slack reactions. But start with 'add' if you prefer.
What if I want to ignore certain reactions?
Tell Notis which reactions matter. You can exclude common ones like laughing faces if they clutter your labels.
Can I combine this with other label rules?
Absolutely. You can have reactions, channels, and other signals all adding/removing labels in Gmail. They work together without conflict.
