Route Gmail emails to Slack by intent using OpenAI and log to Sheets

If your team shares an inbox and someone has to manually read every email to decide where it goes, this workflow takes that off your plate. Emails come in, AI reads them, and the right Slack channel gets notified with a summary and priority level.

Who is this for

Teams that receive a mix of sales inquiries, support requests, and billing questions through a shared inbox. Instead of someone triaging emails by hand every morning, the AI handles it in real time.

How it works

The workflow polls Gmail for new emails every minute. Each email gets sent to OpenAI (gpt-4o-mini by default) with a prompt that classifies it into one of four categories: sales, support, billing, or spam.

The AI also writes a short summary and assigns a priority level (low, medium, or high). A Switch node then routes the message to the correct Slack channel. Spam gets quietly dropped so your team never sees it.

Every email that comes through gets logged to a Google Sheet with its timestamp, sender, subject, category, priority, and AI summary. So you always have a record of what came in and how it was handled.
