This email also includes an unsubscribe link.\n* The unsubscribe flow works similarly via n8n form interface which when submitted disables further scheduled emails to the user.\n\n## How to use\n* Make a copy of sample Airtable here: https://airtable.com/appL3dptT6ZTSzY9v/shrLukHafy5bwDRfD\n* Make sure the workflow is \"activated\" and the forms are available and reachable by your audience.\n\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!\n\nHappy Hacking!" }, "typeVersion": 1 } ], "pinData": {}, "connections": { "Wikipedia": { "ai_tool": [ [ { "node": "Content Generation Agent", "type": "ai_tool", "index": 0 } ] ] }, "Create Event": { "main": [ [ { "node": "Execute Workflow", "type": "main", "index": 0 } ] ] }, "Resize Image": { "main": [ [ { "node": "Set Email Vars", "type": "main", "index": 0 } ] ] }, "Search daily": { "main": [ [ { "node": "Create Event", "type": "main", "index": 0 } ] ] }, "Send Message": { "main": [ [ { "node": "Log Last Sent", "type": "main", "index": 0 } ] ] }, "Should Send?": { "main": [ [ { "node": "Should Send = True", "type": "main", "index": 0 } ] ] }, "Search weekly": { "main": [ [ { "node": "Create Event", "type": "main", "index": 0 } ] ] }, "Execution Data": { "main": [ [ { "node": "Content Generation Agent", "type": "main", "index": 0 } ] ] }, "Generate Image": { "main": [ [ { "node": "Resize Image", "type": "main", "index": 0 } ] ] }, "Set Email Vars": { "main": [ [ { "node": "Send Message", "type": "main", "index": 0 } ] ] }, "Subscribe Form": { "main": [ [ { "node": "Create Subscriber", "type": "main", "index": 0 } ] ] }, "Groq Chat Model": { "ai_languageModel": [ [ { "node": "Content Generation Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "Search surprise": { "main": [ [ { "node": "Should Send?", "type": "main", "index": 0 } ] ] }, "Schedule Trigger": { "main": [ [ { "node": "Search surprise", "type": "main", "index": 0 }, { "node": "Search daily", "type": "main", "index": 0 }, { "node": "Search weekly", "type": "main", "index": 0 } ] ] }, "Unsubscribe Form": { "main": [ [ { "node": "Update Subscriber", "type": "main", "index": 0 } ] ] }, "Create Subscriber": { "main": [ [ { "node": "confirmation email1", "type": "main", "index": 0 } ] ] }, "Should Send = True": { "main": [ [ { "node": "Create Event", "type": "main", "index": 0 } ] ] }, "Window Buffer Memory": { "ai_memory": [ [ { "node": "Content Generation Agent", "type": "ai_memory", "index": 0 } ] ] }, "Content Generation Agent": { "main": [ [ { "node": "Generate Image", "type": "main", "index": 0 } ] ] }, "Execute Workflow Trigger": { "main": [ [ { "node": "Execution Data", "type": "main", "index": 0 } ] ] } } }
