Categorise and label Gmail emails with GPT-4o and OpenAI

Automatically organise your Gmail inbox using AI. This workflow categorises every incoming email and applies Gmail labels, keeping only important emails in your inbox while filing everything else automatically.

Who is this for?
Anyone overwhelmed by email clutter who wants inbox zero without manual sorting.

How it works
Gmail Trigger polls your inbox for new emails every minute
AI Categorisation (GPT-4o) analyses each email and assigns a category such as Action Required, Newsletters, Sales Pitches, Client Communication, Receipts, and more
Filter checks if the email requires your attention or can be auto-filed
Label Management removes non-actionable emails from inbox and applies the appropriate Gmail label
