This workflow automates the creation of email drafts in Fastmail using OpenAI's GPT-4 model. It monitors new emails, generates personalized responses, and uploads them as drafts.

The workflow begins by monitoring a specified IMAP inbox for new, unread emails. Upon detecting a new email, it extracts essential details such as the sender, subject, and body. This information is then sent to OpenAI's GPT-4 to generate a personalized draft response. The workflow connects to the Fastmail API to retrieve session details and mailbox IDs, identifies the Drafts folder, and uploads the generated response as a draft email. This automation streamlines the process of responding to emails, enhancing productivity and ensuring timely communication.
