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.\n\n### How it works\nOn 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.\n\n### Setup\nThis workflow requires that you set up a Notion database or use an existing one with at least the following fields:\n- Title (title)\n- Thread ID (text)\n- Email thread (URL)\n\n\nAdditionally, create a label that will be used to trigger the workflow in Gmail. In this workflow, the label is called \"Notion\"."},"typeVersion":1}],"connections":{"Merge":{"main":[[{"node":"If database page not found","type":"main","index":0}]]},"On schedule":{"main":[[{"node":"Derive last request time","type":"main","index":0}]]},"If checked off":{"main":[[{"node":"Remove label from target email","type":"main","index":0}],[{"node":"Not yet checked off, do nothing","type":"main","index":0}]]},"Find my email address":{"main":[[{"node":"Create database page","type":"main","index":0}]]},"Try get database page":{"main":[[{"node":"Merge","type":"main","index":1}]]},"Derive last request time":{"main":[[{"node":"Get emails from label and last request time","type":"main","index":0}]]},"On updated database page":{"main":[[{"node":"If checked off","type":"main","index":0}]]},"If database page not found":{"main":[[{"node":"Find my email address","type":"main","index":0}],[{"node":"If found, do nothing","type":"main","index":0}]]},"Get emails from label and last request time":{"main":[[{"node":"Try get database page","type":"main","index":0},{"node":"Merge","type":"main","index":0}]]}}}
