Email to Notion

Plenty of things worth tracking still arrive as email: inbound leads, support requests, newsletters and articles you mean to read later, vendor notifications. Notion is where many teams keep that kind of structured record — but copy-pasting each message into a database by hand doesn't scale. You want every email to become a Notion page automatically, with the subject, sender and body already filled in.

Webhook Relay can receive emails as webhooks. You give an inbox a unique address, every message sent to it is parsed into JSON, and a small transform reshapes it into the format the Notion API expects before delivery — no mail server, no glue code, no polling.

How it works

The whole path is a single hop with a transform in the middle:

inbound email  ──▶  Webhook Relay (parse + transform)  ──▶  Notion API  ──▶  new page

When an email hits your Webhook Relay address, it's parsed into a structured JSON document and POSTed to the bucket's outputs. Notion's create-a-page endpoint doesn't understand that shape — it expects a parent, a properties object and optional children blocks — so the transform converts one into the other in flight.

The parsed email looks like this:

{
  "from": "[email protected]",
  "from_name": "Jon Snow",
  "recipient": "<uuid>@in.webhookrelay-mail.com",
  "subject": "Partnership inquiry",
  "date": "Fri, 26 Jun 2026 11:27:41 +0400",
  "text": "plain body",
  "html": "<p>html body</p>",
  "spf": "pass",
  "dkim": "pass",
  "dmarc": "pass",
  "attachments": []
}

See the full payload reference for every field, including to, cc, message_id and the raw headers map.

Setup

1. Create a bucket. This is the container that ties an input to its outputs.

2. Add an email input. Webhook Relay gives you back a unique address of the form <uuid>@in.webhookrelay-mail.com. Anything sent there is parsed and forwarded to the bucket's outputs.

3. Create a Notion integration and share the database. In Notion, create an internal integration to get a secret token, then open your target database, click Connections, and share it with that integration. Copy the database ID from its URL.

4. Add the Notion API as an output. Set the bucket's output destination to https://api.notion.com/v1/pages.

5. Attach the transform. Add the transform function below so the parsed email is reshaped into Notion's format — and the required headers are set — before it's delivered.

6. Send a test email. Email your <uuid>@in.webhookrelay-mail.com address from any client. Within a second or two a new page appears in your database. If it doesn't, open the request log in your dashboard to see exactly what was received and what Notion returned.

The transform

Webhook Relay functions hand you the incoming request body as a string in r.body. Parse it, build the Notion page payload, and write it back with r.setBody — then set the three headers Notion requires:

const e = JSON.parse(r.body);
r.setBody(JSON.stringify({
  parent: { database_id: "YOUR_DB_ID" },
  properties: { Name: { title: [{ text: { content: e.subject } }] }, From: { email: e.from } },
  children: [{ object: "block", type: "paragraph", paragraph: { rich_text: [{ text: { content: e.text || "" } }] } }]
}));
r.setHeader("Authorization", "Bearer " + "YOUR_NOTION_SECRET");
r.setHeader("Notion-Version", "2022-06-28");
r.setHeader("Content-Type", "application/json");

That's the complete bridge: the subject fills the Name title property, the sender lands in a From email property, and the plain-text body becomes a paragraph block in the page. Notion creates the page and returns it.

From here the function is where the real power is. Map more email fields to columns — e.date to a date property, e.from_name to a text property — split the body into multiple blocks, or inspect e.spf / e.from and return early to drop anything you don't want stored.

Get started

Turning inbound mail into Notion pages is one case of a broader pattern: Email to Webhook. Once an email is JSON, you can route it anywhere a webhook can go.

Create a free Webhook Relay account, add an email input, and have leads, support requests and reading-list items flowing into Notion in a few minutes.
