I believe you're looking for something like Outseta (https://www.outseta.com/)

They're a membership platform that supports:

- Payments

- Sign up forms

- CRM

- Authentication

- Content protection

- Email marketing

- Help desk

- Notifications

Pretty amazing if you ask me. I have no affiliation with Outseta, but I do follow the founder on Twitter.

Thank you so much! This appears to be exactly what I am looking for, and then some.

This is exactly why I keep coming back to HN.
