The workflow checks the forward came from you, signed and clean, and a model drafts an answer in your style. The draft comes back to you as a reply, threaded under what you sent. You edit it and send it from your own address. The model only ever sees the one email you forwarded.\n\n### How to set up\n1. In Pidgeon, create an address for the agent (type agent, *only people who wrote first*).\n2. Make a key with **send** on that one address. Add it as a Pidgeon API credential.\n3. Pick the address in the trigger, and put your own addresses and three of your sent emails in **Your settings**.\n4. Add your Anthropic credential, or swap the model for another.\n\n### Requirements\nA Pidgeon account, an n8n instance on a public HTTPS URL, and a model credential.\n\n### How to customise\nForward is for \"answer this\". To have the agent answer the original sender itself, replace the last node with **Pidgeon → Save a draft** to `{{ $json.from }}`, which needs an address that may write to anybody.\n\nSetup and the other templates: https://pidgeon.ai/docs/n8n?utm_source=n8n"
