Automate Email Draft Replies with Fastmail & OpenAI GPT-4

This n8n workflow automates email response drafting for Fastmail users by integrating IMAP monitoring, OpenAI's GPT-4, and Fastmail's JMAP API. It triggers on new unread emails, extracts sender, subject, and body details, then prompts GPT-4 to create tailored replies. The draft is prepared with original metadata and uploaded directly to your Fastmail Drafts folder.

Key benefits include massive time savings for high-volume inboxes, consistent professional responses, and personalization without manual effort. It's ideal for busy professionals handling customer support, sales inquiries, or personal correspondence, reducing response times from hours to minutes.

Use cases span solopreneurs managing client emails, support teams scaling replies, and executives delegating routine communication. Prerequisites include IMAP setup, Fastmail API credentials, and OpenAI key. Configuration involves updating node credentials and endpoints for seamless operation.
