Gmail can read your emails and attachments to train its AI, unless you opt out

Gmail can read your emails and attachments to train its AI, unless you opt out, a change quietly rolled out by Google that Malwarebytes highlights in its November 2025 coverage. According to Malwarebytes, Google has reportedly started auto-enrolling users to allow access to private messages and attachments for AI training, with features powered by Gemini AI designed to make Gmail smarter.

The article notes that some settings are switched on by default and that users can opt out by turning off Smart Features in two separate places: Gmail/Chat/Meet settings and Google Workspace smart features settings. It emphasises that fully disabling AI training requires both locations to have the features turned off. To aid readers, the piece provides a step-by-step guide to opt out and cautions that privacy controls may be rolled out gradually.
