What is the Gmail recommended unsubscribe alert and how does it work?

Summary

The Gmail recommended unsubscribe alert is a feature that leverages machine learning to identify users who may want to unsubscribe from email lists due to inactivity. This alert manifests as a banner at the top of the email, offering a one-click unsubscribe option. This prompt aims to help users manage their inboxes effectively and encourages senders to prioritize list hygiene and user engagement. Senders should ensure their emails are authenticated, use List-Unsubscribe headers, monitor engagement metrics, and provide valuable, personalized content to avoid triggering the alerts.
