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.

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, sharing this register's Substack-style build spec:
1. Write and publish posts, some free, some paid-only.
2. Send new posts via a transactional email API to subscribers.
3. Stripe Subscriptions gating paid content behind a login check on the post page.
4. A public archive of free posts.
That's a real, complete newsletter platform. Out of scope: built-in discovery and recommendations (readers finding you through the platform's own algorithm), which doesn't come with a self-hosted build, and podcast or audio-post support, which adds this register's own podcast-hosting scope on top.
