Abstract: Methods for delivering rich media content to a user within an email system via a dedicated media channel. An email system receives an email message associated with rich media content from a registered sender for delivery to a recipient. To improve the recipient's viewing experience, the email system ensures that the rich media content is loaded in a rich media database before delivering the email message to the recipient. When the recipient reads the email message, the email system delivers the rich media content to the recipient from the rich media database via a dedicated media channel efficiently and at a low cost.

Abstract: A system is disclosed for serving advertisements to a user of a client device. Based on a user requesting to view an email message in their inbox, the system provides the email message to the user. At least one header field in the header portion of the email message is scanned and data is extracted from at least one header field. The extracted data is delivered to an advertising server, which selects an advertisement that is relevant to the extracted data and delivers the relevant advertisement back to the system. The relevant advertisement is delivered to the user.
