Task Assignment Reminder: Never Assigned Work Gets Lost
You just assigned a task. ClickUp notifies them. Notis reminds them in Slack. That's it. The work doesn't disappear into the void because they missed a Slack notification.
Trigger
Task Assignee Updated
Triggers when an assignee is added to or removed from a task. `changes[]` carries `AssigneeAddChange` and/or `AssigneeRemoveChange` entries. A single event may bundle multiple adds and/or removes — for example when a workflow re-routes a task between two users in one operation.
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
Assigned work gets lost because the assignee didn't see the ClickUp notification or missed the context of what they're supposed to do by when.
- Assignees see new work in their most-active app (Slack)
- Reminder persists if they're away or busy
- No manual follow-up needed to confirm task landed
- Reduce anxiety about whether assignments actually happened
Setup
Build it in a few focused steps.
- 1Connect ClickUp and Slack to Notis via the portal
- 2Create an automation: 'When a task assignee is updated in ClickUp, send a reminder in Slack to the assignee'
- 3Choose how soon to remind them (in 5 minutes, in 1 hour, tomorrow morning, etc.)
- 4Select 'Task Assignee Updated' as the trigger
- 5Test by assigning a task in ClickUp to yourself
Questions about this workflow
What if a task has multiple assignees?
Notis creates separate reminders for each new assignee, or groups them if that's clearer for your workflow.
Can we remind people at a specific time?
Yes. In your prompt, specify when reminders should fire: 'remind them in 1 hour', 'remind them at 9am tomorrow', etc.
What if someone is already overloaded?
That's a process decision. Some teams use this to alert leads who then delegate; others use it for individuals. Notis follows whatever you ask.
