Newsletter Draft Starter for Next.js
DraftLetter is an AI newsletter generator and SaaS starter built with Next.js 16, React 19, Tailwind CSS 4 and Node 20.x. Designed for developers who want a production-ready newsletter-draft workflow without hand-rolling the core logic and UI from scratch.
DraftLetter ships as a deployable starter: you get a working baseline app, clear setup and deployment docs, and a structure you can extend for your own use or client work.
Introductory pricing
DraftLetter is currently offered at launch pricing for early buyers. As the product matures the price will be in line with the value of building and documenting a similar tool from scratch.

You stay in control of
- Styling, copy, and brand integration for your own product or client

- Hosting, authentication, billing, and long-term maintenance
The generator is intentionally stateless in this starter. This allows you to wire in your own database, authentication, and billing where it makes sense for your business.

FAQs
-
In this context, “production-ready” means each starter ships as a deployable baseline app that runs reliably in a real environment. You get a working core flow, a clear README, and deployment guidance. These are starters, not turnkey SaaS businesses – you still customise features, styling, auth, billing, and integrations to fit your own product or client project.
-
Developers and technical founders who want a solid starting point instead of building every project from a blank repo.
It is not intended as a consumer product; it’s a starter aimed at technical buyers.
-
Most starters use a modern web stack (for example: Next.js, React, TypeScript, Tailwind CSS, and a hosted database or API). Each product page lists the exact stack, versions, and any external services required.

Yes. At TwelveVoltsCo we launch starters when they are stable, documented, and deployable. New products will appear here as they are ready, not before.
-
Your purchase includes the current version of the starter as described on this page.
If we discover a defect that stops the shipped features from working as described (for example, the app no longer runs or a documented flow is broken), we will issue a corrected version and make it available to existing customers at no extra cost.
Broader enhancements, new features, or new editions (for example, versions with built-in auth or billing) may be released as separate products.
Built to fix, built to work.
