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}]]}}}
