Activate the workflow What It Does The Smart Inbox Organizer workflow automates email management by combining Gmail triggers with AI-powered classification. Every time a new email arrives, the workflow captures its content and standardizes key fields like sender, subject and body. An AI agent then analyzes the email and assigns it to one of four categories: Work, Personal, Financial or Newsletter. Based on this classification, the workflow routes the email to the appropriate action path. It not only applies Gmail labels automatically but also logs structured data into Google Sheets for tracking and analytics. Additionally, financial emails are treated with higher importance by creating a task in Google Tasks for manual review, ensuring nothing critical is missed.
