Disclosed herein are system, method, and computer program product embodiments for automatically transitioning a user from a call to action (CTA) to an enrollment interface. An embodiment operates by receiving a request from a user's device to display web content. The requested web content is displayed along with a CTA. When the CTA is selected by the user, an e-mail client associated with the user's device automatically opens, generates an electronic message based on the selected CTA, and populates a recipient address and a code associated with the CTA within the electronic message. Upon its receipt, the electronic message is processed by enrolling the user in a campaign associated with the CTA based on the code and the user's e-mail address. An electronic message is generated and sent to the user's e-mail address that contains a first hyperlink to the campaign associated with the CTA and a second hyperlink to an associated privacy policy.
