For the banishment of all doubt, no, Google isn't scraping the contents of your email inbox in order to train its AI models. However, that doesn't mean Gmail is free of Gemini, and sooner or later you'll need to decide your own personal boundaries with AI.
Google announced at the start of the year that Gmail would be entering the Gemini era. This ushered in AI overviews for your inbox, as well as the Help Me Write feature that allows floundering users to draft emails with AI assistance. Gemini is used to sift through all the data in your inbox in order to summarise information or give relevant insights.
