Users on your website can have different sets of interaction options. Your customers can be either Subscribers (those who receive newsletter), regular Users (those who have account to purchase deals) or Casual users (those who make instant purchases).
Subscription and user registration are two independent processes. Usually, when a new website is being launched, its main focus is subscribers. That is why the subscription page is the landing on websites that are not yet fully live. The subscribers are meant to become registered users in the future – this may happen when they receive a deal they are interested in. Though, not every subscriber becomes a user, it will take quite a significant period of time. The scenario can be different: new visitor comes to already functioning website, sees the deal he/she likes, registers as user and purchases the deal. This user may or may not become a subscriber.
To sum up:
A person creates an account on the site on-purpose – to purchase some deal. By imposing him/her to subscribe (making an automatic subscription against user's intention) we break the terms of Anti-SPAM policy and violate human rights. That is why the process of user registration is isolated from subscription.
