Automate Email Triage with GPT-4.1 and Gmail Auto-Responses

This workflow is designed for solo operators and small teams who receive a mix of inbound emails and need efficient triage without constant inbox monitoring. It uses GPT-4.1 to classify emails into four categories: Agency Lead, Course Request, Paid Collaborations, and Miscellaneous. Based on the classification, it applies the appropriate Gmail label, sends an auto-reply, or drafts a response. Additionally, it logs Paid Collaboration contacts into Google Sheets for future follow-up.
