The workflow removes any existing processing label from the email thread to prepare it for a fresh AI pass.\n3. An AI Agent (powered by Gemini) reads the email thread, checks the Google Calendar, and drafts a reply along with a suggested label.\n4. A Switch routes the output: emails needing a draft reply are processed through a JavaScript code node that builds an HTML signature before saving a Gmail draft; other outcomes skip directly to label retrieval.\n5. The workflow fetches the appropriate Gmail label for the response and applies it to the thread, marking the message as unread so it appears ready for human review.\n\n### Setup steps\n\n- - [ ] Connect a **Gmail OAuth2** credential to all Gmail and Gmail Trigger nodes (Gmail - Nouveaux emails, Get a message, Remove label from thread, Draft into label, Get label for response, Labelliser, Mark a message as unread).\n- - [ ] Connect a **Google Gemini (PaLM)** API credential to the GEMINI sub-node inside the AI Agent.\n- - [ ] Connect a **Google Calendar OAuth2** credential to the AGENDA sub-node inside the AI Agent.\n- - [ ] Configure the Gmail Trigger node with the correct label/filter to watch for new emails requiring AI handling.\n- - [ ] Review and update the label names used in 'Remove label from thread', 'Get label for response', and 'Labelliser' to match your Gmail label setup.\n- - [ ] Customize the HTML signature in the 'Code in JavaScript' node to match your desired email signature.\n- - [ ] Review the Switch1 routing conditions to ensure they match the AI Agent's output structure from the PARCER (structured output parser).\n\n### Customization\n\nYou can adjust the AI Agent's system prompt to change the tone or structure of drafted replies. The Switch1 conditions can be modified to add more routing branches (e.g., forward, archive, escalate). The HTML signature in the Code in JavaScript node can be updated with your personal or company branding."
