Google will stop scanning your Gmail inbox in order to send out targeted ads
While Google didn't say when it will stop the Gmail scanning, it did say that it will continue to display targeted ads. Instead of mining data from your Gmail inbox, Google will look at the YouTube videos you watch, the Google searches you request, the websites you visit and the apps you use. Sure, you can go into Google settings and turn off ad personalization to stop the targeted ads, but data will still be collected by the Alphabet subsidiary.
With the scanning of your Gmail inbox, Google might find that you receive a lot of email related to smartphones. Therefore, targeted ads from handset manufacturers would be deemed more likely to catch your attention. It is a great way for advertisers to more efficiently reach potential customers.
