Can I vibecode Brevo?

The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Brevo, send a low-volume newsletter and transactional messages with clear consent records. The hard boundary is deliverability infrastructure, multichannel messaging, crm, automation, and support, plus deliverability, growth network, and integrations.

the prompt

Build a personal replacement for Brevo 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 with clear consent records, compose and send a low-volume newsletter and transactional messages, publish a web archive, and report basic delivery and click events.
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.
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.

why people still pay

People still pay for Brevo 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.
