Who is this workflow for? Efficiently managing email responses can significantly enhance productivity. This n8n workflow leverages the power of OpenAI Assistant to automatically generate draft replies for emails labeled in Gmail. By seamlessly integrating with Gmail threads, it ensures your responses are timely and contextually relevant..

What does this workflow do?

Step 1: Trigger and Label Monitoring

The workflow initiates at regular intervals (default every 1 minute) to scan Gmail for emails tagged with a specific label, such as “AI”. This ensures that only designated messages are processed.

Step 2: Email Content Extraction

Once labeled emails are identified, their content is extracted and forwarded to the OpenAI Assistant node. This node utilizes AI to analyze the email and generate a relevant draft response.

Step 3: Draft Generation

The OpenAI Assistant formulates a reply based on the email content. This draft is then converted to HTML to ensure proper formatting within Gmail.

Step 4: RFC Formatting and Encoding

The generated draft is formatted according to the RFC standards for email messages. It is then encoded appropriately to maintain compatibility with Gmail’s threading system.

Step 5: Thread Integration

The encoded draft is attached to the original Gmail thread, ensuring that the response maintains the continuity of the conversation.

Step 6: Label Management

To prevent the workflow from reprocessing the same email, the initial label (e.g., “AI”) is removed after the draft is created. This step ensures the workflow remains efficient and avoids duplication.
