  • Patent number: 10783208
    Abstract: A service provider may determine that an electronic message sent from a first user device of a first user to a second user device of a second user includes a URL. The service provider may cause the URL to be unfurled, resulting in a preview of the URL, using a combination of a server-based process and a client-based process and one or more policies. Based on the policies, a cloud-based unfurling service may attempt to obtain metadata associated with the URL in order to unfurl the URL. If the server-based unfurling process is unable to unfurl the URL, the first device and/or the second device may obtain the metadata and unfurl the URL. As a result, the recipient of the message (e.g., the second user) may view an unfurled URL that includes a preview of a website corresponding to the URL (e.g., a title/headline, representative text, images, videos, etc.).
