Never Send an Invoice to a Bad Email Again
Bounced invoices create invoice tracking chaos. Notis validates every recipient email before you send, catching typos and undeliverable addresses.
Trigger
Page Properties Updated
Triggers when properties of a Notion page are updated. Customer optionally scopes with at most one of: - data_source_id: any row in this data source - page_id: this specific page - parent_page_id: any page whose immediate parent is this page With none set, fires for any property change in the workspace the integration has access to. Adding a column to a data source fires this trigger once per existing row. Customers can branch on `data.updated_properties` (array of property IDs) to filter downstream.
Action
Email Verification API
Tool to verify email addresses including syntax validation, domain existence, and email account verification. Use when you need to validate an email address before sending messages or storing contact information.
Why this helps
Tracking down undelivered invoices and following up on bounces creates administrative work that pulls you away from revenue.
- Prevents invoice delivery failures
- Stops bounced invoice tracking work
- Validates emails before sending
- Improves payment collection speed
Setup
Build it in a few focused steps.
- 1Connect Notion and Addressfinder to Notis.
- 2Ask Notis: 'When an invoice recipient email is set, verify the email address.'
- 3Select 'Page Properties Updated' trigger on your invoices database.
- 4Notis alerts you to invalid emails in Slack.
- 5Test by entering an invalid email and confirming Notis flags it.
Questions about this workflow
Can I still send invoices to flagged emails?
You can, but Notis will have warned you. Usually it's worth fixing the email first.
How quickly are emails validated?
Instantly, as soon as the email field is filled in.
What if I'm sending to a Gmail address that's temporarily down?
Notis validates the domain exists. Temporary outages don't affect validation.

Supported Triggers and Actions
Notis builds workflows that link Notion to Addressfinder. A trigger fires from one place; an action lands in another.
Notion triggers
Addressfinder actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
AU Address Autocomplete
Tool to perform interactive search of Australian addresses from the AddressFinder database. Use when you need to search for and autocomplete Australian addresses based on partial input.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get AU Address Metadata
Tool to retrieve full metadata for an Australian address selected from the Address Autocomplete API. Use when you need complete address details including GPS coordinates and census data.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
AU Address Verification
Tool to verify Australian addresses against PAF/GNAF databases. Use when you need to validate or standardize an Australian address and retrieve associated metadata like coordinates, statistical identifiers, and GNAF data.
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.
AU Location Autocomplete
Tool to perform interactive autocomplete search for Australian streets, suburbs, and states. Use when you need to find or suggest Australian locations based on partial input.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Get AU Location Metadata
Tool to retrieve comprehensive metadata for an Australian location (street, suburb, or state) selected from the Location Autocomplete API. Use when you need detailed information about a specific Australian location including coordinates, street details, suburb, state, and postcode.
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.
Email Verification API
Tool to verify email addresses including syntax validation, domain existence, and email account verification. Use when you need to validate an email address before sending messages or storing contact information.
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.
International Address Autocomplete
Tool to search for international addresses using autocomplete functionality. Use when users need to find and select addresses in supported countries (AU, BE, CA, CZ, DK, FR, DE, IE, NZ, NL, PT, SG, ES, SE, GB, US). Returns address IDs that can be used with the Address Metadata API to retrieve full address details.
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.
Get International Address Metadata
Tool to retrieve full metadata for an international address selected from the Address Autocomplete API. Use when you need complete address details including street metadata and optional GPS coordinates for addresses outside your primary region.
