Launches reach zero because founders have no email list and start too late
Problem Breakdown
Founders hear "you need an email list" after their first flop, then start collecting emails with no plan. A month later they have 40 subscribers and nothing to send them. On launch day they email 40 people and wonder why it feels like shouting in an empty room.
The problem has two parts: starting too late, and having no system that turns traffic into subscribers and subscribers into launch-day buyers. Newsletter tools give you a form and a send button, not a growth system.
Meanwhile there's no easy way to see which pages, posts, or communities actually convert visitors into subscribers, so founders keep pouring effort into channels that produce nothing.
Solution Architecture
Build a pre-launch list machine. The maker describes their product and audience; the tool generates a lead magnet (a useful checklist, mini-course, or template), builds a landing page for it, and sets up a five-email nurture sequence that warms subscribers before launch.
It then tracks which channels bring subscribers that actually open and click, not just any subscribers, and tells the founder where to spend their limited promotion hours.
Your Build Prompt
You are an experienced full-stack developer. Build a complete, working version of the following tool. Do not ask questions, do not leave placeholders, do not write TODOs. Make real, working code that runs on the first try. TOOL: Launches reach zero because founders have no email list and start too late WHAT IT MUST DO: Build a pre-launch list machine. The maker describes their product and audience; the tool generates a lead magnet (a useful checklist, mini-course, or template), builds a landing page for it, and sets up a five-email nurture sequence that warms subscribers before launch. CORE FEATURES TO BUILD: 1. A lead magnet generator that creates a useful checklist, template, or mini-course for the niche 2. A hosted landing page builder optimized for email capture 3. A five-email nurture sequence drafted and scheduled automatically 4. Channel attribution: which sources bring subscribers who actually engage 5. A launch-day email flow with pre-written announcement sequences 6. A simple dashboard showing list growth and readiness score before launch TECH STACK: Next.js, TypeScript, Resend, OpenAI API, PostgreSQL RULES: - Use strict TypeScript everywhere. Define proper types and interfaces. No any. - Validate all user input with a schema library (Zod or equivalent). - Handle errors cleanly: show a clear message to the user, log the detail for the developer. - Handle loading and empty states in every view. - Make it fully responsive: mobile, tablet, and desktop. - Keep the design clean and professional: clear typography, good spacing, real icons (Lucide), smooth hover states. SETUP: Start from a fresh Next.js (App Router) TypeScript project and build the features above one by one, verifying each runs before moving to the next. Finish with a short summary of what was built and how to run it.
