After creating a newsletter, from the administrative control panel:

• Hover your mouse over “Subscriptions” and click on “Add a Product”
• Select “Type” as “Subscription Product” if you wish to charge a recurring fee for access to the newsletter, otherwise select “Type” as “Single Purchase” to only charge the user once for access to the newsletter.
• Input a name and description for this product.
• Input the price for the product.
• If this is a subscription product, input a timeframe for renewal in the “Recurring Timeframe” section. Some examples:
  • Every 1 month: 00 01 00 00 00 00
  • Every 3 months and 15 days: 00 03 15 00 00 00
• Scroll down to the section entitled “Newsletter Subscriptions” and tick the checkbox next to the newsletter that you wish to charge for.
• Click on “Add Product”

On the next screen, a list of products will then appear with the new product included. Find the product ID and use this to create a payment link for the newsletter. You can also allow users to purchase this product from the cart catalog:
