Google is souping up Gmail with features from its Gemini 3 AI app. Here's what to know — including how to opt out.

Google has made big changes to Gmail, the world’s most popular email service and now more than 2 billion users must decide how they want to use the updated platform. The changes mark one of the biggest shifts in Gmail in more than 20 years.

This is a marked change for Gmail, more than twenty years after the platform launched. It has generated plenty of coverage as a response, but it comes with caveats — only a limited number of changes over a limited period of time. For anyone stuck with their twenty-year-old high school or college email address, it will come as a relief.
