Send approved proposals by mail from Notion
Keep the final proposal and its mailing step close together by using the Notion page update as the cue.
Trigger
Page Content Updated
Triggers when the body content of a Notion page is 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 page content edit in the workspace the integration has access to. Notion aggregates content edits within a short window (~60s typical).
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
Why this helps
A proposal can be ready to send while the mailing task remains buried in notes or a separate checklist.
- Connect proposal readiness with its delivery step.
- Reduce duplicate entry across tools.
- Use the approved PDF and recipient context from the work record.
Setup
Build it in a few focused steps.
- 1Connect Notion and Docupost to Notis once in the portal.
- 2Create an automation asking Notis to mail the approved proposal PDF when the page content indicates final approval.
- 3Select Page Content Updated for the proposal page or data source and choose a channel for run reports.
- 4Test with one real approved proposal page and verify recipient and PDF before sending.
Questions about this workflow
Will every content edit send a letter?
The trigger reports page content updates. Describe the final approval condition clearly and validate the first run to ensure only approved proposals are mailed.
Can it use a PDF stored in Notion?
The action requires a PDF. State which approved document Notis should use and confirm the file is accessible and correct before sending.

Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

All Page Events
Triggers when any Notion page is created or updated across the workspace.
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.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
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.
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.
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.
