Owners of white-label applications have the ability to send notifications to users of their mobile application.
Technical connection to these services is made during the creation of your mobile app so the Messages feature is ready for use in GO. In order to send a notification, click the "New message" button and fill the header and body boxes then click on "Save" and "Send".
You can narrow your target audience either by platform -iOS vs. Android- or by campaign -only users who scanned this campaign's targets will receive notification-.
Mobile app users will receive the notification as soon as sending process is complete though it may take some time if your app has many users, so be patient or just keep on working in another section of the GO platform while your message is being sent.
