Paid newsletter via Zoho Campaigns

Paid newsletter via Zoho Campaigns

Hi,
Is it possible to set up a paid newsletter via Zoho Campaigns? I would like to create a form with a link to payment gateway, then have those contacts added to a separate group to whom I can send a specific newsletter?

Ideally I would like a tiered subscription model - Some people can join for free to get a few articles, while some people can pay a certain fee to get access to more articles and special content. 

Is this sort of sign up possible, where customers can choose free/paid, and if they choose paid, they go to a payment gateway? And their respective emails get put into "free" or "paid" groups, so the newsletter can be sent to the right group?
