what AI can build

Collect and manage subscribers, compose and send branded compliant campaigns, publish a web archive, and report basic delivery and click events.

The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Campaign Monitor, compose branded campaigns, manage subscribers, and report delivery and clicks. The hard boundary is template editor, deliverability, journeys, agency features, and integrations, plus deliverability, growth network, and integrations.

The honest tradeoff

why people still pay

People still pay for Campaign Monitor 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.

Catalog estimate
Build a personal replacement for Campaign Monitor 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 and manage subscribers, compose and send branded compliant campaigns, 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.

questions

Can AI replace Campaign Monitor?

Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: template editor, deliverability, journeys, agency features, and integrations, inbox-placement expertise. Validate the prompt against your own acceptance criteria before committing.

How much does Campaign Monitor cost?

Campaign Monitor is listed at about $12/month (Lite, checked 2026-07-31), or $144 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Campaign Monitor?

Honestly: template editor, deliverability, journeys, agency features, and integrations; inbox-placement expertise; advanced automations; commerce integrations; recommendation and ad networks. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Campaign Monitor?

Yes — Listmonk (Mature open-source newsletter and mailing-list manager.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
