Hi Jignesh, The best way to do this is to create a web application (web form) in Adobe Campaign with the Service Subscription widget in it and then insert a link to the web form in your e-mail. There is an example of this in the training environment; do you have access to a training account? You can also use a file to upload a list of new subscribers or use an API call to subscribe an individual directly from your web site. Regards, Linda
