Check a new contact source as it appears
A new data source can bring a fresh set of addresses into your system. Check the list early and keep the outcome easy to review.
Trigger
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.
Action
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.
Why this helps
New sources can multiply contact records and create uncertainty about which ones are ready for outreach.
- Check a source near its introduction to the workspace.
- Reduce manual uncertainty across multiple addresses.
- Get one report to guide the next cleanup step.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mails so to Notis once through the portal.
- 2Create an automation with a plain-language instruction to identify available emails in the new contact data source, validate them in bulk, and report the outcome.
- 3Select the Notion Data Source Created trigger and mention the relevant contact-source context in the prompt.
- 4Choose a channel for run reports and test with a real source containing a small email list.
Questions about this workflow
Is this the same as creating a database?
No. Data Source Created fires when a data source is added, including to an existing database; Database Created signals container creation.
What if the source is empty?
Ask Notis in the prompt to skip the validation action if the new source has no email addresses.

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.
