It uses a two-path approach:\n\nPath A : For contacts with email history, it searches Gmail threads and uses GPT-5 Nano to extract phone numbers, social media profiles, and websites from email signatures and message content.\n\nPath B (Web Search): For contacts without email history, it extracts their domain, validates it's not a generic provider (f.e. gmail.com), then uses Brave Search API to find their website's contact page. And HTML parser extracts details from the result.\n\n## Setup steps\n1. Create a Google Sheet using this template structure: [Make a copy here](https://docs.google.com/spreadsheets/d/1ox0cP_v8UuonAFr3eXkOFRlBb_P86NRedEaK4fss5cA/edit?usp=sharing)\n2. Connect credentials: Gmail, OpenAI API, Brave Search API, Google Sheets\n3. Update node \"SelectTabCC\" with your Sheet ID\n4. Customize excluded domains in \"ValidDomain?\" if needed\n5. Run manually to process all sent emails"},"typeVersion":1},{"id":"cd90fc19-4899-4c4f-9a65-252a5690494e","name":"Sticky Note7","type":"n8n-nodes-base.stickyNote","position":[-1328,-336],"parameters":{"color":5,"width":672,"height":464,"content":"## GetInboxMessages\nSearches Gmail for last existing conversations with this contact.\n\nWhat it pulls:\n- Entire email threads (not just one message)\n- Includes: body, signatures, quoted replies\n- Both sent AND received messages"},"typeVersion":1},{"id":"ab87283e-ce39-4ed1-9659-ca9c2a613d5e","name":"Sticky Note8","type":"n8n-nodes-base.stickyNote","position":[-656,192],"parameters":{"color":5,"width":320,"height":272,"content":"For contacts with NO email history, extract domain from email address.\n\nIf we have valid domain - let's try to find contact pages."},"typeVersion":1}],"active":false,"pinData":{},"settings":{"executionOrder":"v1"},"versionId":"f0b7ff51-f1b9-4294-b905-030605f45230","connections":{"3s":{"main":[[{"node":"GetInboxMessages","type":"main","index":0}]]},"Merge":{"main":[[{"node":"WriteToDB","type":"main","index":0}]]},"GetHTML":{"main":[[{"node":"Aggregate","type":"main","index":0}]]},"Aggregate":{"main":[[{"node":"Loop Over Items1","type":"main","index":0}]]},"WriteToDB":{"main":[[{"node":"Loop Over Items","type":"main","index":0}]]},"HTMLParser":{"main":[[{"node":"WriteToDB","type":"main","index":0}]]},"MailParser":{"main":[[{"node":"ValidDomain?","type":"main","index":0}]]},"SelectTo&CC":{"main":[[{"node":"Remove Duplicates","type":"main","index":0}]]},"GetClusters1":{"main":[[{"node":"HaveClusters","type":"main","index":0}]]},"HaveClusters":{"main":[[{"node":"Loop Over Items1","type":"main","index":0}],[{"node":"ReturnContactFromMailParser","type":"main","index":0}]]},"ValidDomain?":{"main":[[{"node":"SearchWebsite","type":"main","index":0}],[{"node":"No Operation, do nothing1","type":"main","index":0}]]},"SearchWebsite":{"main":[[{"node":"GetClusters1","type":"main","index":0}]]},"InboxMessages?":{"main":[[{"node":"SelectImportantFields","type":"main","index":0}],[{"node":"MailParser","type":"main","index":0}]]},"Loop Over Items":{"main":[[{"node":"No Operation, do nothing","type":"main","index":0}],[{"node":"3s","type":"main","index":0}]]},"GetInboxMessages":{"main":[[{"node":"InboxMessages?","type":"main","index":0}]]},"LoadSentMessages":{"main":[[{"node":"SelectTo&CC","type":"main","index":0}]]},"Loop Over Items1":{"main":[[{"node":"HTMLParser","type":"main","index":0}],[{"node":"GetHTML","type":"main","index":0}]]},"OpenAI Chat Model":{"ai_languageModel":[[{"node":"Information Extractor","type":"ai_languageModel","index":0}]]},"Remove Duplicates":{"main":[[{"node":"Loop Over Items","type":"main","index":0}]]},"Information Extractor":{"main":[[{"node":"Merge","type":"main","index":0}]]},"SelectImportantFields":{"main":[[{"node":"Information Extractor","type":"main","index":0}]]},"No Operation, do nothing1":{"main":[[{"node":"WriteToDB","type":"main","index":0}]]},"ReturnContactFromMailParser":{"main":[[{"node":"WriteToDB","type":"main","index":0}]]},"When clicking ‘Execute workflow’":{"main":[[{"node":"LoadSentMessages","type":"main","index":0}]]}}}
