Without, this could be annoying for both the user and the recipient!\n\n### How it works\n* A scheduled trigger checks your google calendar for sales meetings which happened a few days ago.\n* For each event, gmail search is used to figure out if a follow-up message has been sent or received from the other party since the meeting. If none, we want to remind ourselves to reengage the lead.\n* For leads applicable for follow-up, we first get an AI Agent to find available meeting slots in the calendar.\n* These slots and reminder are sent to the user via send-and-approval mode of the gmail node. The user replies in natural language either picking a slot, suggesting an entirely new slot or declines the request.\n* When accepted, another AI Agent books the meeting in the calendar with the proposed dates and lead.\n\n### How to use\n* Update all calendar nodes (+subnodes) to point to the right calendar. If this is a shared-purpose calendar, you may need to either filter or create a new calendar.\n* Update the gmail nodes to point to the right accounts.\n\n### Customising the template\n* Not using Google? Swap out for Microsoft or otherwise.\n* Try swapping out or adding in additional send-for-approval methods such as telegram or whatsapp.\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!"}, "typeVersion": 1}, {"id": "46ef7220-49ea-4dfc-8e4c-ce7da5119daf", "name": "Send for Human Approval", "type": "n8n-nodes-base.gmail", "position": [1660, 80], "webhookId": "76b88312-1c54-482e-abdd-e699159577f0", "parameters": {"sendTo": "=<your-email-here>", "message": "={{ $json.message }}", "options": {}, "subject": "=Book a follow-up meeting with {{ $('Only Follow Ups').item.json.attendees.find(x => !x.self).email }}?", "operation": "sendAndWait", "responseType": "freeText"}, "credentials": {"gmailOAuth2": {"id": "Sf5Gfl9NiFTNXFWb", "name": "Gmail account"}}, "typeVersion": 2.1}], "pinData": {}, "connections": {"Model": {"ai_languageModel": [[{"node": "Meeting Availability Agent", "type": "ai_languageModel", "index": 0}]]}, "Model1": {"ai_languageModel": [[{"node": "Meeting Booking Agent", "type": "ai_languageModel", "index": 0}]]}, "Output": {"ai_outputParser": [[{"node": "Meeting Availability Agent", "type": "ai_outputParser", "index": 0}]]}, "Meetings": {"ai_tool": [[{"node": "Meeting Booking Agent", "type": "ai_tool", "index": 0}]]}, "Availability": {"ai_tool": [[{"node": "Meeting Availability Agent", "type": "ai_tool", "index": 0}]]}, "Mark as Seen": {"main": [[{"node": "Loop Over Items", "type": "main", "index": 0}]]}, "Get Past Events": {"main": [[{"node": "Mark as Seen", "type": "main", "index": 0}]]}, "Loop Over Items": {"main": [[{"node": "Only Follow Ups", "type": "main", "index": 0}], [{"node": "Get Emails Since", "type": "main", "index": 0}]]}, "Only Follow Ups": {"main": [[{"node": "Meeting Availability Agent", "type": "main", "index": 0}]]}, "Generate Message": {"main": [[{"node": "Send for Human Approval", "type": "main", "index": 0}]]}, "Get Emails Since": {"main": [[{"node": "Flag to Follow Up", "type": "main", "index": 0}]]}, "Schedule Trigger": {"main": [[{"node": "Get Past Events", "type": "main", "index": 0}]]}, "Flag to Follow Up": {"main": [[{"node": "Loop Over Items", "type": "main", "index": 0}]]}, "Send for Human Approval": {"main": [[{"node": "Meeting Booking Agent", "type": "main", "index": 0}]]}, "Meeting Availability Agent": {"main": [[{"node": "Generate Message", "type": "main", "index": 0}]]}}}
