receiving data representing attributes of the electronic message to be generated for the particular intended recipient; and

in response to receiving the data representing the attributes of the electronic message:

generating, by a processor, custom content triggering data based on the attributes of the electronic message, the custom content triggering data representing at least a dynamic portion of customized content to be added subsequently into the electronic message while the electronic message is rendered for display only to the intended recipient;

generating the electronic message content, wherein the generated electronic message content includes the custom content triggering data; and

sending the electronic message that includes the generated electronic message content to the particular intended recipient.

9. The method of claim 8 , wherein generating the electronic message content includes generating predetermined content.

10. The method of claim 8 , wherein the electronic message comprises email or SMS text messages.

11. The method of claim 8 , wherein the attributes of the electronic message include a message identifier and attributes of an intended recipient of the electronic message.

12. The method of claim 11 , wherein the generated electronic message content is HTML and the custom content triggering data is included in an HTML image tag.

13. The method of claim 11 , wherein the generated electronic message content includes an embedded API function call, and the custom content triggering data is included as an argument in the API function call.

14. A computer program product, stored on a non-transitory computer readable medium, the program product comprising instructions that when executed by one or more computers cause the one or more computers to perform operations implementing automated generation of electronic message content that is customized for only a particular intended recipient of an electronic message, the operations comprising:

receiving, from a client device, an API function invocation in response to an opening of the electronic message and invoked by the electronic message after the opening of the electronic message, and while the electronic message is being rendered for viewing, wherein the API function invocation comprises custom content triggering data as an argument, the content triggering data comprising at least a message recipient identifier configured to enable retrieval of stored user profile data representing the message recipient
