Reply Draft with OpenAI Assistant (Automated Reply Draft Generation Based on OpenAI Assistant)
This workflow automatically generates reply drafts by monitoring emails with specific labels in Gmail. It passes the content of the latest emails to an intelligent assistant, which generates high-quality replies and inserts them into the original email thread in a properly formatted manner, finally removing the triggering label. This process significantly enhances the efficiency of email responses, making it particularly suitable for scenarios like customer service and sales that require quick email handling, thereby reducing the manual workload and achieving intelligent and automated email replies.
