Request an account-user check when your workflow needs it
When your Notion process reaches an account review checkpoint, send a request to Notis and retrieve the MailerSend user list on demand.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
List webhooks
Tool to retrieve a list of webhooks. use when you need to list and paginate all configured webhooks, optionally filtering by domain.
Why this helps
Account reviews tend to happen only when someone remembers, making it harder to keep operational checks consistent.
- Run a user inventory check at a workflow checkpoint.
- Make periodic review available on demand.
- Keep account discovery connected to the process that needs it.
Setup
Build it in a few focused steps.
- 1Connect Notion and MailerSend to Notis once through the portal.
- 2Create an automation in the portal or ask Notis in a connected channel to create it.
- 3Give Notis one plain-language instruction to retrieve MailerSend users when your Notion process requests an account review.
- 4Choose an incoming webhook trigger and select a channel for run reports.
- 5Test with one real review request from your workflow.

Supported Triggers and Actions
Notis builds workflows that link Notion to Mailersend. A trigger fires from one place; an action lands in another.
Notion triggers
Mailersend actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Sending Domain
Tool to add a new sending domain to mailersend. use when you need to register and configure a domain before sending emails.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create SMTP User
Tool to create a new smtp user. use after domain setup to obtain smtp credentials.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Create API Token
Tool to create a new api token. use when you need to generate a token with specific permissions in mailersend.
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.
Create Webhook
Tool to create a new webhook for a mailersend domain. use after you have a domain id and need to receive event notifications like sent, delivered, opened, etc.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Delete Webhook
Tool to delete an existing webhook. use when the webhook is no longer needed. returns empty response on successful deletion (http 204).
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.
Get API Quota
Tool to retrieve current api usage quota. use when monitoring api rate limits to avoid exceeding allowed calls.
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.
Get Domain
Tool to fetch information for a specific sending domain. use when you need to verify domain status and dns configuration after setup or changes.
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.
List Domain Recipients
Tool to list recipients for a domain. use after obtaining the domain id to view recipients with optional pagination.
