Creating an Email Course Service

I like watching the Tech Lead and he recently submitted a Video that showed how he setup a nice email service. It's about sending emails with code challenges to train to get a job at FAANG.
Here is a link to the video: https://www.youtube.com/watch?v=1jVMy0lpAcI

I think it might be a good idea to create a no-code version of what he described.
The features:

• Landingpage with a field to enter an email address
• CMS to edit and schedule the mails
• A subscribe button powered by Stripe

Do you know something that does what he talks about already, leave a comment. I like to try a content format once this is done.
