Yahoo has announced that it is testing several new artificial intelligence features in its email service, including a shopping feature called "Shopping Saver." This feature allows users to retrieve gift cards and promo codes directly from their inboxes. Additionally, the email composition assistant and email summarization features have been enhanced. These functionalities are built on Google Cloud's AI platform, marking Yahoo's efforts to enhance the value of its products. If these new features are well-received by users, they could help retain more Yahoo Mail users.
