If you've had trouble keeping up with the latest and greatest templates beign published daily, this workflow can save you a lot of time!\n\n### How it works\n* A scheduled trigger pulls a list of subscribers (email and category preferences) from an Excel workbook.\n* We work out unique categories amongst all subscribers and only fetch the latest n8n website templates from these categories to save on resources and optimise the number of API calls we make.\n* The fetched templates are summarised via AI to produce a short description which is more suitable for our email format.\n* For each subscriber, we filter and collect only the templates relevant to their category preferences (as defined in the Excel) and ensure that duplicate templates or those which have been \"seen before\" are omitted.\n* A HTML node is then used to generate the email newsletter. HTML emails are the perfect format since we can add links back to the template.\n* Finally, we use the Outlook node to send the email digest to the subscriber.\n\n### How to use\n* Populate your Excel sheet with 3 columns: name, email and categories. Categories is a comma-delimited list of categories which match the n8n template website. The available categories are AI, SecOps, Sales, IT Ops, Marketing, Engineering, DevOps, Building Blocks, Design, Finance, HR, Other, Product and Support.\n* To subscribe a new user, simply add their email to the Excel sheet with at least one category.\n* To unsubscribe a user, remove them from the sheet.\n* If you're not interested in paid templates, you may want to filter them out after fetching them.\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!"}, "typeVersion": 1}], "pinData": {}, "connections": {"Merge": {"main": [[{"node": "For Each Subscriber", "type": "main", "index": 0}]]}, "Aggregate": {"main": [[{"node": "For Each Category", "type": "main", "index": 0}]]}, "Parse Rows": {"main": [[{"node": "Get Unique Categories", "type": "main", "index": 0}, {"node": "Merge", "type": "main", "index": 0}]]}, "Collect Fields": {"main": [[{"node": "Aggregate", "type": "main", "index": 0}]]}, "Append Category": {"main": [[{"node": "For Each Category", "type": "main", "index": 0}]]}, "Get Subscribers": {"main": [[{"node": "Parse Rows", "type": "main", "index": 0}]]}, "Schedule Trigger": {"main": [[{"node": "Get Subscribers", "type": "main", "index": 0}]]}, "Combine Workflows": {"main": [[{"node": "With User Reference", "type": "main", "index": 0}]]}, "Flatten Workflows": {"main": [[{"node": "Merge", "type": "main", "index": 1}]]}, "For Each Category": {"main": [[{"node": "Flatten Workflows", "type": "main", "index": 0}], [{"node": "Workflows to Items", "type": "main", "index": 0}]]}, "OpenAI Chat Model": {"ai_languageModel": [[{"node": "Workflow Summarizer", "type": "ai_languageModel", "index": 0}]]}, "Workflow to Items": {"main": [[{"node": "Remove Already Seen", "type": "main", "index": 0}]]}, "Has New Workflows?": {"main": [[{"node": "Generate HTML Template", "type": "main", "index": 0}], [{"node": "No Operation, do nothing", "type": "main", "index": 0}]]}, "Workflows to Items": {"main": [[{"node": "Workflow Summarizer", "type": "main", "index": 0}]]}, "Categories to Items": {"main": [[{"node": "Fetch Latest 10 per Category", "type": "main", "index": 0}]]}, "For Each Subscriber": {"main": [[{"node": "Has New Workflows?", "type": "main", "index": 0}], [{"node": "Get Relevant Workflows", "type": "main", "index": 0}]]}, "Remove Already Seen": {"main": [[{"node": "Combine Workflows", "type": "main", "index": 0}]]}, "With User Reference": {"main": [[{"node": "For Each Subscriber", "type": "main", "index": 0}]]}, "Workflow Summarizer": {"main": [[{"node": "Collect Fields", "type": "main", "index": 0}]]}, "Get Unique Categories": {"main": [[{"node": "Categories to Items", "type": "main", "index": 0}]]}, "Generate HTML Template": {"main": [[{"node": "Send Daily Digest", "type": "main", "index": 0}]]}, "Get Relevant Workflows": {"main": [[{"node": "Workflow to Items", "type": "main", "index": 0}]]}, "Fetch Latest 10 per Category": {"main": [[{"node": "Append Category", "type": "main", "index": 0}]]}}}
