Currently we are following the Adobe recommended way of subscribing new users by doing a double opt-in through an email leading to a landing page where the user then confirms their intent to subscribe to our services. However, this has led to a high failure rate in opting in and customers complaining that they think they have subscribed, but in actuality they have not since they have only followed the link in the email and then not confirmed a second time upon reaching the landing page.
Due to this we would like to simplify our opt-in process. What we would like to do is whitelist the user simply by following the link in the email without having to interact on the landing page. Now I have tried to tinker around with the emails and landing pages and cannot find any way of accomplishing this. I also tried creating a workflow that checks the opt-in delivery for clicks to whitelist users but as each opt-in generates a new delivery that also does not work.
So, my question is if there is any way of doing this, or some kind of workaround to make it possible? If not, is it a functionality that is planned to be implemented down the road?
