Send Deadline Reminders via Email When Due Dates Are Set

When a due date is added or updated in Notion, the assigned person gets a reminder email--no more forgotten deadlines hiding in the task database.

Trigger

Page Properties Updated

Triggers when properties of a Notion page are updated. Customer optionally scopes with at most one of: - data_source_id: any row in this data source - page_id: this specific page - parent_page_id: any page whose immediate parent is this page With none set, fires for any property change in the workspace the integration has access to. Adding a column to a data source fires this trigger once per existing row. Customers can branch on `data.updated_properties` (array of property IDs) to filter downstream.

Why this helps

Due dates are set in Notion but people don't see them. Email inboxes are where reminders live. Connecting Notion dates to email keeps deadlines visible.

  • Deadlines stay in people's active inbox, not buried in Notion
  • Instant notification when dates change
  • Reduces missed deadlines
  • Less context-switching between apps

Setup

Build it in a few focused steps.

  • 1Connect Notion and Agent mail to Notis.
  • 2Tell Notis: 'When the due date property is set or changed on any task in my task database, send the assignee an email with the task name, due date, and priority.'
  • 3Scope to your main task database.
  • 4Pick a channel for run reports and test by setting a due date on a task.

Questions about this workflow

Will assignees get an email every time the due date is modified?

Yes--this creates a paper trail in email, which some teams like. You can set a 'confirmed' flag to avoid repeated emails.

Can I send reminders at specific intervals (1 day before, 1 week before)?

That's a separate workflow using notis_cron scheduling for more precise timing.

What if there's no assignee?

You can route it to a project lead or leave it unassigned in your prompt.

Comment Created

Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.

TriggerInstant

New Comment

Triggers when a new comment is added to a specified Notion block or page.

TriggerPolling

Database Created

Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.

TriggerInstant

Data Source Created

Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.

TriggerInstant

Data Source Schema Updated

Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
