Should you build your own MailerLite?
Send newsletters, build forms, and run a small welcome sequence
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For MailerLite, send newsletters, build forms, and run a small welcome sequence. The hard boundary is deliverability, editor polish, landing pages, automations, and integrations, plus deliverability, growth network, and integrations.
ENOriginal research content in English. Original prompt preserved in English.
Build a personal replacement for MailerLite 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 through forms, compose and send compliant newsletters and a small welcome sequence, 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.

What would building your own look like?
Collect subscribers through forms, compose and send compliant newsletters and a small welcome sequence, publish a web archive, and report basic delivery and click events.
What you will need
- Amazon SES account
- verified sending domain
- PostgreSQL
- public HTTPS deploy target
- DNS access
People still pay for MailerLite 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.
