Claim:
A method of sending an enhanced email comprising: providing an email with an intended email address; modifying the intended email address into a readdressed email address in the email by: adding a signature selection code to a top level domain name of the intended email address to create an interim email address with an invalid top level domain name; and separately from adding said signature selection code, modifying the interim email address for email readdressing comprising appending a server domain name preceded by a period to the interim email address, wherein the readdressed email address comprises the intended email address, the signature selection code, the period, and the server domain name, wherein the server domain name is at an end of the readdressed email address; providing an Internet connected server having said server domain name for receiving said email based on said readdressed email address and sending said enhanced email based on said intended email address; providing, on said server, a database associating said signature selection code with corresponding add-on programming code; receiving said email at said server based on said readdressed email address; extracting, at said server, said signature selection code and said intended email address from said email; inserting into said email, at said server, the add-on programming code corresponding to said signature selection code to create said enhanced email; and sending, from said server, said enhanced email based on said intended email address, whereby a sender of said email can specify said add-on programming code to insert through said signature selection code comprised in said readdressed email address and thus selectively creates said enhanced email for sending to a recipient of said email.
