Find related email from a Slack reaction
Use a reaction as a lightweight cue to check whether an email conversation needs attention too.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Fetch emails
Fetches a list of email messages from a gmail account, supporting filtering, pagination, and optional full content retrieval.
Why this helps
A reaction can signal that something needs follow-up, but the matching email context may still be buried in Gmail.
- Use an existing Slack signal to prompt an email context check.
- Find related messages without manually switching to Gmail.
- Keep the follow-up tied to the reacted-to message.
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Gmail once in the Notis portal.
- 2Create an automation that searches Gmail using context from the reacted-to message.
- 3Pick Message Reaction Added as the trigger.
- 4Choose a report channel and test with one real reaction.
Questions about this workflow
Can I limit which reactions start this?
The trigger supports optional filtering by channel and emoji name. Select any available trigger options during setup.
Does a reaction guarantee a Gmail match?
No. Matches depend on what context the Slack message provides and what is present in Gmail.
