Hello! My name is Adam. I'm a poet. I want to create a paid newsletter with three types of subscriptions. The first one is free, where the user will get their email weekly. Second one is £10/month where users will get emails daily. The third is like the second one but for a lifetime. They'll pay £300. I'm looking to create a landing page with these three options. I find it hard to find any instructions on how to do that. Please help. Thanks in advance. Adam.
