Validate prospect email addresses as they enter Notion
Add a prospect in Notion and have Mailboxlayer check the email address, so you can focus outreach on contacts that can be reached.
Trigger
New Page
Triggers when a new page is added to a Notion database.
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
Manual checks interrupt prospect research and make it easy to send follow-ups to a mistyped address.
- Catch invalid or malformed prospect addresses early.
- Keep email checking inside the flow of adding new leads.
- Reduce avoidable outreach retries caused by address mistakes.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mailboxlayer to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to set it up conversationally.
- 3In one plain-language instruction, ask Notis to check the email address on each new prospect record and report the result.
- 4Choose the Notion New Page trigger for the prospect database and select a channel for run reports.
- 5Test it with one real prospect record.

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.
