Newsletters

Should you build your own Substack?

Publish posts and send email from a self-owned list without recreating discovery or payments

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Substack, publish posts and send email from a self-owned list without recreating discovery or payments. The hard boundary is reader network, recommendations, app distribution, payments, and brand familiarity, plus deliverability, growth network, and integrations.

The complete prompt
Build a closest honest personal substitute for Substack in an empty repository.
Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Amazon SES; do not offer alternative stacks.
The core loop is: collect subscribers on a self-owned list, compose and send compliant email posts, publish a web archive, and report basic delivery and click events without recreating discovery or payments.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Implement subscriber import, double opt-in, unsubscribe, suppression, tags, and consent timestamps.
Create a Markdown campaign editor with HTML and plain-text previews.
Queue sends through SES with retries, rate limits, idempotency, and resumable batches.
Process delivery, bounce, complaint, open, and click webhooks without logging message content.
Publish a simple issue archive and subscriber preference page.
Add test sends, seed-list checks, DNS setup guidance, exports, and backups.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out a newsletter recommendation marketplace.
Deliberately leave out ad sales and payment infrastructure.
Deliberately leave out complex lifecycle automation and enterprise deliverability support.
Finish by running the tests and listing the exact commands used.

What you will need

Why paying can still make sense

People still pay for Substack because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface.
