Scheduled Notion Digest Email via Gmail

## Send labeled email to a Notion database
This workflow sends the contents of an email to a Notion database. The email must be labeled with a specific label for the workflow to trigger. The email subject will be the title of the Notion page, and a snippet of the email body will be the content of the Notion page. The email link will be added to the Notion page as a property.

### How it works
On scheduled intervals, find all emails with a specific label. For each email, check if the email already exists in the Notion database. If it does not exist, create a new page in the Notion database, otherwise do nothing. When the task in the Notion database is checked off, the label will be removed from the email.

### Setup
This workflow requires that you set up a Notion database or use an existing one with at least the following fields:
- Title (title)
- Thread ID (text)
- Email thread (URL)


Additionally, create a label that will be used to trigger the workflow in Gmail. In this workflow, the label is called "Notion".
