I'm trying to figure out the best way to configure the newsletter subscription form built using WFFM which after form submission will send an e-mail to a user with an activation link to confirm the subscription.
I found this post which describes the solution accurately but unfortunately, my project Sitecore license is CMS-only and I'm afraid I cannot use the out of the box solution. I'm using Sitecore 8.2 update 5.
Currently, I'm not able to even add the "Add contact to contact list" save action to the form with error
This action cannot be added. Your configuration does not support it.
I believe it's caused by the lack of xDb.
Is there any simple way to implement the functionality in CMS-only mode or it has to be a separate mini-project with completely custom development?
