Check contact emails on pages under your hub
A new subpage under your partner or project hub can trigger a quick Mailcheck verification for its listed email.
Trigger
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Action
Verify Email Address
Tool to verify provided email address. use after obtaining user email input.
Why this helps
New subpages are easy to create and easy to overlook when they contain a contact to follow up with.
- Keep new contact pages under a chosen hub in a consistent routine.
- Reduce manual checking after creating a subpage.
- Preserve project context while verifying contact details.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mailcheck to Notis once through the portal.
- 2Create an automation in the portal or describe it to Notis conversationally.
- 3Use one prompt to verify a contact email on a new subpage under the chosen hub.
- 4Select Page Added to Page and choose the parent page as the trigger scope.
- 5Choose a report channel and test with one new subpage containing an email.
Questions about this workflow
Does this apply to nested pages at any depth?
The trigger is for a page added under a specified parent page. It describes an immediate parent relationship.
Can the same hub hold other types of pages?
Yes. Explain in the prompt which subpages contain contacts whose emails should be checked.

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.
