1. Email Trigger (IMAP): Configure your IMAP credentials and the inbox to monitor.
2. Markdown: This node automatically converts the textHtml from the IMAP trigger to Markdown.
3. Email Summarization Chain: This node uses the OpenAI Chat Model (deepseek-chat in this case) to summarize the content provided by the Markdown node. The prompt is set to generate a concise summary.
4. Write email: This node uses the OpenAI node (gpt-4o-mini) to generate the email response based on the summarized email. The systemMessage guides the AI to be professional, concise, and within a word limit. The prompt is `Write the text to reply to the following email:

{{ $json.response.text }}. Note: $json.response.textis likely referring to the output of theEmail Summarization Chainnode. 5. **Set Email text:** This node takes the output from theWrite emailnode and assigns it to anemailvariable for later use. 6. **Approve Email:** This node sends an email toinfo@n3witalia.comcontaining the original email's HTML and the AI-generated response for human review. It's configured tosendAndWait, meaning the workflow will pause here until a response is received or a timeout occurs (though not explicitly shown in parameters). 7. **Approved?:** This IFnode checks theapprovedfield from theApprove Emailnode's output. Ifapprovedis true: - **Send Email:** The AI-generated email response is sent to the original sender of the incoming email. Ifapproved` is false, the workflow path ends.
