Automatically alert Slack when spreadsheet metrics change
Stop checking your dashboard every hour. Notis monitors aggregate metrics (sum, count, average) in your Google Sheets and posts alerts to Slack whenever they change, so your team knows instantly when something shifts.
Trigger
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Tracking key business metrics across spreadsheets requires constant vigilance and creates decision fatigue. Missing a critical metric change can mean delayed action or missed opportunities.
- Remove the burden of manually monitoring spreadsheet metrics
- Get instant visibility when key numbers move
- Make faster decisions based on real-time data
- Keep your entire team aligned on performance changes
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Slack to Notis (one-time setup).
- 2Create a new automation with this prompt: 'When the total sales in my Google Sheets tracker changes, post the new total and the change amount to #[channel-name].'
- 3Select 'Aggregate Metric Changed' as the trigger and specify your metric (sum, count, average).
- 4Choose the Slack channel for alerts.
- 5Test by updating a value in your sheet and watch the alert appear in Slack.
Questions about this workflow
What metrics can I track?
Any aggregate: sum (total revenue), count (number of leads), average (mean response time), minimum, or maximum. Notis works with columns that have numeric data.
Does the automation trigger on every change?
Yes. Every time the aggregate result changes, Notis posts an update. If you want less noise, mention it in your prompt: 'Only alert when the total changes by more than $1000.'
Can I track multiple metrics?
Create separate automations for each metric. This keeps alerts organized and reduces alert fatigue.
