Keep blocked Trello work from going quiet
Let Notis create a follow-up reminder when a card becomes blocked, giving the team a clear moment to return to it.
Trigger
Card Updated Trigger
Triggered when a specific card is updated
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Blocked work can wait for someone else while everyone assumes another person is following up.
- Make stalled work visible for a deliberate follow-up.
- Reduce ambiguity about whether someone is watching a blocker.
- Create a nudge that helps the team return to the issue.
Setup
Build it in a few focused steps.
- 1Connect Trello and Slack to Notis once through the portal.
- 2Create an automation in the portal or tell Notis what outcome you want.
- 3Ask Notis to create a Slack reminder when a card update indicates a blocker, with a useful revisit time.
- 4Select the Trello card-updated trigger and a channel for run reports.
- 5Test by updating one real card with a blocker and review the reminder.
