Check contact details on new subpages
When a new contact or project subpage appears under your chosen hub, validate its listed email before it is needed.
Trigger
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Action
Validate Single Email
Tool to validate a single email address. use when you need to check deliverability and quality details before sending an email.
Why this helps
Subpages can be created quickly during focused work, but small data-quality tasks are easy to leave behind.
- Use a familiar Notion hub as the scope for checks.
- Catch invalid contact details close to page creation.
- Get a lightweight reminder through the run report.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mails so to Notis once through the portal.
- 2Create an automation with an instruction to validate an email on each new subpage under the chosen hub and report the result.
- 3Select the Notion Page Added to Page trigger for the appropriate parent page.
- 4Choose a channel for run reports and test by adding a real subpage with an email address.
Questions about this workflow
Does this cover nested descendants too?
The trigger covers a new subpage under the specified parent page. Set the scope to the relevant parent and verify the behavior with a real example.
What if the subpage has no email?
Instruct Notis to skip validation when no email address is present.

Supported Triggers and Actions
Notis builds workflows that link Notion to Mails so. A trigger fires from one place; an action lands in another.

Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Retrieve Batch Results
Tool to retrieve results of a bulk validation job. use after submitting a batch and you have its id.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Validate Bulk Emails
Tool to validate multiple email addresses in bulk. use when you need to confirm deliverability of a list of emails at once.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Validate Single Email
Tool to validate a single email address. use when you need to check deliverability and quality details before sending an email.
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.
