email conversations between your own inboxes. It generates friendly multi-message conversations using OpenAI, stores them in `warmup_conversations`, builds a daily send plan in `warmup_queue`, and assigns randomized send times within a safe daily window. Messages are sent using the correct Gmail OAuth credential for each inbox, replies happen in the same thread, and warmup emails are automatically marked as read to mimic human inbox activity.\n\n## Setup steps\n1) Create 3 Data Tables: `cold_email_accounts`, `warmup_conversations`, `warmup_queue`\n2) Add at least 2 inboxes to `cold_email_accounts` with `email`, `cred_id`, and `warmup_daily_limit`\n3) Create one Gmail OAuth2 credential per inbox and paste the credential ID into `cred_id`\n4) Add your OpenAI API credential to the OpenAI node\n5) Enable schedule triggers and execute once to test\n" }, "typeVersion": 1 } ], "connections": { "Flatten message list": { "main": [ [ { "node": "Insert messages into warmup_queue", "type": "main", "index": 0 } ] ] }, "If warmup
