What This Workflow Does

This workflow is built for inbox triage. Instead of manually sorting every email, the workflow evaluates the message content with Gemini and applies a clean label system so priority mail is surfaced immediately and low-value mail stays out of the way.

Priority Detection

High-priority mail is separated quickly so important requests are not buried under the rest of the inbox.

Work Mail Routing

Internal and client-related messages are tagged as work-related for better follow-up and focus.

Promotion Sorting

Promotional mail gets a dedicated label so it can be reviewed later instead of interrupting deep work.

Always-On Automation

The workflow runs continuously, so the inbox stays organized even when new mail arrives all day.

Workflow Flow

1. Gmail Trigger

Every new incoming email starts the automation without manual intervention.

2. Gemini Classification

The content is evaluated by Google Gemini so the workflow can decide what label is most appropriate.

3. Conditional Labeling

The workflow routes the email into high-priority, work-related, or promotional buckets.

4. Label Application

The correct Gmail label is applied automatically and the inbox stays structured going forward.
