Customer Match allows you to upload a list of email addresses, which can be matched to signed-in users on Google in a secure and privacy-safe way. From there, you can build campaigns and ads specifically designed to reach your audience. Users can control the ads they see, including Customer Match ads, by opting out of personalized ads or by muting or blocking ads from individual advertisers through Google Ads Settings.
Starting today, Universal App Campaigns will be available to all developers and advertisers as a new AdWords campaign type that helps you connect with app users across Google Search, Google Play, YouTube, and the Google Display Network (GDN).
