Can I code this? A Newsletter With Paid Subscriptions
Writing and sending posts shares Mailchimp's buildable core. Gating some posts behind a Stripe subscription is well-documented; deliverability at scale is the one recurring challenge every email tool on this register shares.

Effort: a weekendRunning cost: $0/mo to start
Why CanICodeThis says Borderline
The writing and sending core is the same buildable pattern as any email tool — a composer and a transactional email API
Stripe Subscriptions gating paid-only posts behind a login check is a well-documented pattern
A public archive of free posts is ordinary content rendering
The parts that'll cause problems
Deliverability at scale is an ongoing reputation problem tied to sending domain and volume history, not something you build once and forget
A built-in discovery network (readers finding you through the platform's own recommendations) doesn't come with a self-hosted build
Podcast/audio post support adds real hosting scope beyond text

The build prompt
Build me a newsletter platform with paid subscriptions: write and publish posts, send them via a transactional email API to subscribers, and gate some posts behind a Stripe Subscriptions paywall (checkout plus a login check on the post page). A public archive of free posts. SQLite behind a small API.
