Paid Content?

Hi everyone,

I want to provide some subscription based content. It actually doesn't have to be on the drupal site at all, but it seems sensible to see if there is an option. Ideally I'd like to:

• Charge a monthly subscription
• Send out an email to alert subscribers of new content

My first thought was to find a service that would host an email newsletter for me, with a subscription model. That's still a decent option I think, but I would also like ot know of any Drupal specific solutions, or indeed any other kind of service that might work.

Thanks for any ideas!
