Email and Slack Stay Connected
A message arrives in your #clients channel about a recent proposal. Notis automatically retrieves the matching Gmail thread so you have both the Slack context and the full email history.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Fetch Message by Thread ID
Retrieves messages from a gmail thread using its `thread id`, where the thread must be accessible by the specified `user id`.
Why this helps
Messages in Slack reference emails, but you can't access them without leaving Slack and searching Gmail. Critical context gets lost.
- View full email context without leaving Slack
- Avoid missing details from broken conversations
- Make better decisions with all information visible
- Reduce context-switching and mental load
Setup
Build it in a few focused steps.
- 1Connect Slack and Gmail.
- 2Create an automation: 'When a message is posted in a channel, fetch the related Gmail thread.'
- 3Notis will use Channel Message Received as your trigger and Fetch Message by Thread ID as your action.
- 4Configure which channels trigger this and how Notis should match them to Gmail threads.
- 5Test by posting a message in a channel; Notis will surface related emails.
Questions about this workflow
How does Notis know which thread to fetch?
It searches by sender name, email address, or keywords in the Slack message. You configure the matching logic.
Will this flood Slack with emails?
Notis posts a summary or link, not the full thread. You can click through if you want full details.
Does this work for all channels?
You can enable it for specific channels (e.g., #clients, #projects) or all channels. Your choice.
