email collection

Please let me know if there's currently a way to work this with the paywall. If not, the idea is:

A temporary 'subscription' option where a non-subscriber could be offered a limited-time access to hard-paywalled content if they submitted their email address to be added to a list.

For example, if we had a new product we wanted to promote by email campaign, and we wanted to quickly build a distribution list, we turned on a month-long access to paywalled content on the website for non-subscribers. When they hit the paywall on the article, they would be prompted to purchase a subscription or - for a limited time - submit their email for that new product promotion.
