Email messages include HTML content with one or more hyperlinks referring to a network-connected dynamic content server. The hyperlinks are accessed upon rendering of the email on a client device, triggering a request to a dynamic content server. The dynamic content server determines a content item to be served in response to the request. The dynamic content item determination may be based on factors including the identity of the requester, the email communication in which the hyperlink is embedded, recent activities or behavior on the part of the requester, and/or known preference or demographic information associated with the requester. The request can be directed to a selected content item stored within a content delivery network, for transmission back to the requester and display to the user within the email. ## Claims ### Claim 1 A computerized method, at a dynamic publication system, for publishing dynamic content via email, the computerized method including operations comprising at least: receiving an email template at an email server;

receiving, via a network, requests for the dynamic content at a dynamic content server in response to respective renderings of the email message on the recipient user devices; allocating, in real-time, different dynamic content of the dynamic content to different recipient user devices of the recipient user devices as the email message is respectively rendered on or viewed by users of the recipient user devices, the allocating the different dynamic content comprising: detecting, among the requests for the dynamic content, an originating IP address of a first recipient user device of the recipient user devices rendering the email message and requesting the dynamic content; performing a location lookup based on the detected originating IP address to determining a current location of the first recipient user device; making or tailoring a dynamic content determination based on the current location; determining a degree of persistence for the different dynamic content, wherein the degree of persistence for the different dynamic content is included in a mapping of the one or more hyperlinks and a specified period of time for when each of the different dynamic content expires after a first rendering on one of the recipient user devices;

receive, via a network, requests for the dynamic content at a dynamic content server in response to respective renderings of the email message on the recipient user devices; allocate, in real-time, different dynamic content of the dynamic content to different recipient user devices of the recipient user devices as the email message is respectively rendered on or viewed by users of the recipient user devices, the different dynamic content allocated by: detecting, among the requests for the dynamic content, an originating IP address of a first recipient user device of the recipient user devices rendering the email message and requesting the dynamic content; performing a location lookup based on the detected originating IP address to determine a current location of the first recipient user device; making or tailoring a dynamic content determination based on the current location; determining a degree of persistence for the different dynamic content, wherein the degree of persistence for the different dynamic content is included in a mapping of the one or more content hyperlinks and a specified period of time for when each of the different dynamic content expires after a first rendering on one of the recipient user devices; tracking a number of times the email message is opened on the recipient user devices including each of the different dynamic content; determining performance levels of content items in the dynamic content; based on the determined performance levels, allocating a greater proportion of subsequent requests for the dynamic content to a highest-performing dynamic content of the dynamic content; based on the determined performance levels, eliminating a further dynamic content of the dynamic content that is performing poorly; select, from the different dynamic content, personalized content for the users of the recipient user devices based on at least one habit of the users; and transmit the personalized content to at least one of the batch of recipient user devices. ### Claim 10 (depends on 9) The system of claim 9, wherein the at least one processor is further configured to determine a particular content item with which a particular request for dynamic content is associated based on a message ID contained within the particular request for dynamic content. ### Claim 11 (depends on 10) The system of claim 10, wherein the at least one processor is further configured to: relaying information from the particular request for dynamic content to a personalization server and receiving, from the personalization server, a content item ID;
