Validate contact emails in a focused Notion discussion
Choose a Notion page discussion where contact details surface and have Notis check each relevant address with Mailboxlayer.
Trigger
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Action
Check Email Validity
Tool to validate a single email address. use when you need to check syntax, domain, smtp, and meta-flags.
Why this helps
A busy project thread can bury a contact email before anyone verifies it or acts on it.
- Focus checks on a specific page or block discussion.
- Keep contact details from slipping through a busy project conversation.
- Receive the validation result in your selected reporting channel.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mailboxlayer to Notis once in the portal.
- 2Create the automation in the portal, or ask Notis to create it in a conversation.
- 3In one instruction, ask Notis to check contact email addresses in comments on the chosen discussion and report the results.
- 4Select New Comment for the specified Notion page or block and choose a channel for run reports.
- 5Test with one real comment in that discussion.
Questions about this workflow
How does this differ from a workspace-wide comment trigger?
New Comment is intended for a specified Notion block or page, while Comment Created can cover comments more broadly.
Does this find an email if the comment has none?
The instruction should ask Notis to check relevant email addresses when present; the action validates a single address.

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.
