Visually track your sent emails in Slack
When you send an important email, Notis adds an emoji reaction to the related Slack message, creating a visual way to track what's been communicated to whom.
Trigger
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Teams struggle to know what's been officially communicated via email versus discussed in Slack, leading to confusion about what's been committed to.
- Create a visual category system for sent emails without manual tagging
- Quickly see which Slack discussions have resulted in formal email communication
- Build team muscle memory around which emoji represents 'this got emailed out'
- Reduce confusion about the status of team communications (Slack vs. email)
Setup
Build it in a few focused steps.
- 1Connect Gmail and Slack to Notis.
- 2Create an automation: ask Notis 'When I send an email related to a Slack message, add a reaction to that message' or use the portal.
- 3Describe the outcome: 'Add a checkmark emoji or the emoji [emoji-name] to mark that this discussion resulted in an outgoing email.'
- 4Select the trigger: Email Sent.
- 5Choose a Slack channel for run reports.
- 6Test by sending an email that references a recent Slack message and verify the emoji reaction appears.
Questions about this workflow
How does Notis know which Slack message to react to?
Describe it in your prompt. Common triggers: Slack messages that mention the email recipient, messages with keywords matching the email subject, or messages from people you're responding to.
Can I use different emoji for different types of emails?
Absolutely. Set up multiple automations with different prompts: 'For client emails, use checkmark' and 'For internal emails, use envelope'. Each automation can have its own emoji.
Does this work for all sent emails or just specific ones?
You control the scope. In your prompt, specify which emails trigger the reaction (e.g., 'only to external recipients' or 'only if the subject mentions a Slack thread').
