# How to Vibe Code Your Own Flodesk (and Stop Paying for It)

> Email marketing and checkout platform built for creators

- Site: https://flodesk.com
- Category: Email Marketing & Creator SaaS
- Platforms: Web app
- Verdict: **Solid side project** (62/100 vibecodeable)
- Estimated effort: 3-4 weeks of focused development

## Verdict

You can build a personal email marketing and form builder clone with AI coding agents, but maintaining inbox deliverability will test your patience.

Replicating the visual editor, form builder, and database schema for subscribers is straightforward with modern Next.js and AI tools. However, treating this as a serious utility rather than a toy means confronting the brutal reality of email deliverability. Setting up SPF, DKIM, DMARC, and avoiding the spam folder for your own newsletters requires real infrastructure discipline. Furthermore, building an email layout builder that compiles down to clean, cross-client compatible HTML tables requires meticulous prompt engineering.

### What you can't replicate

- Established sender domain reputation
- Built-in viral loop across 100,000+ active creator accounts
- Instant trust and brand equity with recipient mail servers

## What it does

Design-first email marketing, landing pages, opt-in forms, and lightweight e-commerce checkouts for creators and small businesses.

### Core features

- Visual drag-and-drop email builder with layout blocks
- Custom brand fonts and color palettes
- Subscriber management and segmentation
- Multi-trigger automated email sequences (workflows)
- Embedded, pop-up, and link-in-bio lead capture forms
- Stripe-integrated checkouts for digital products and subscriptions

## The business

### Pricing

- Free: $0/mo
- Lite: $25/mo
- Pro: $28/mo
- Everything: $54/mo

Founded 2018.
Team size: 50-75.

## The hard parts

- Email deliverability infrastructure (maintaining SPF, DKIM, DMARC, feedback loops, and IP reputation at scale)
- Cross-client HTML/CSS rendering compatibility for visual emails across Outlook, Gmail, and Apple Mail
- Reliable asynchronous workflow engine handling timed delays and conditional branching without dropping events
- Multi-tenant Stripe Connect integration with tax compliance and instant digital product delivery

## How to vibe code Flodesk

### Prerequisites

- Node.js (free): Required runtime for running Next.js and frontend tooling.
- GitHub (free): Code repository and deployment source control.
- Resend account (free tier (3k emails/mo)): Transactional email API to handle outbound delivery with managed DNS and DKIM.

### Recommended AI tools

- Claude Code: Best-in-class multi-file agentic coding tool for scaffolding the database, backend workflows, and drag-and-drop editor components.
- Cursor: Ideal for fine-tuning the complex React-based visual layout editor and component CSS.

### Stack

- Frontend: Next.js with Tailwind CSS and shadcn/ui
- Backend: Next.js Server Actions & API Routes
- Database: Turso (SQLite at the edge for subscriber lists and templates)
- Auth: better-auth
- Payments: Stripe
- Other: Resend (email sending), Inngest (workflow automation engine)

### Hosting

- Vercel (Hosting the Next.js frontend, API endpoints, and serverless actions): $0/mo (Hobby tier)
- Turso (Serverless SQLite database for subscribers, segments, and templates): $0/mo (Free tier)

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js 16 project with Tailwind CSS 4, shadcn/ui, better-auth, and Turso database client configured for user authentication and subscriber data models.

```
Create a new Next.js 16 app with TypeScript, Tailwind CSS 4, and App Router. Set up Turso client connectivity using @libsql/client. Define Prisma or Drizzle schema models for users, subscribers (id, email, status, custom_fields, tags, created_at), forms (id, user_id, title, settings, layout_json), email_templates (id, user_id, name, json_blocks, html_content), and campaigns (id, user_id, template_id, subject, status, sent_at). Integrate better-auth for email/password authentication. Ensure proper environment variable configuration and clean project structure.
```

2. **Audience & Segment Management Dashboard** — Build the subscriber management interface allowing users to view, tag, filter, import via CSV, and export their subscriber base.

```
Build a dashboard page in Next.js App Router for managing subscribers. Create a data table component with shadcn/ui featuring pagination, search by email, filtering by status (active, bounced, unsubscribed), and batch tagging. Add a CSV import modal that parses uploaded files using PapaParse and bulk-inserts subscribers into Turso with server actions. Implement a metrics summary header showing total active subscribers, growth rate, and unsubscribe counts.
```

3. **Visual Drag-and-Drop Email Builder** — Develop a minimalist visual builder interface where users can stack layout blocks (text, images, buttons, countdown timers, polls) and compile them into responsive email HTML.

```
Build a visual email builder component in React. Provide a sidebar of content blocks: Header, Paragraph, Image, Button, Countdown Timer, and Poll. Allow users to drag or click to add blocks into a central canvas, reorder them, and edit their properties (colors, padding, font family, link URLs) in a right-side inspector panel. Implement an export function that compiles the block state tree into clean, responsive HTML email markup using nested <table> structures for maximum email client compatibility (Outlook, Gmail, Apple Mail).
```

4. **Forms & Lead Generation Embeds** — Implement public-facing hosted landing pages and embeddable form snippets that collect subscriber data and assign them to specific tags.

```
Create a form builder module where users can design inline, pop-up, and link-in-bio capture forms linked to specific tags. Build a public route `/f/[formId]` that renders the hosted form with custom branding colors and fonts. Implement form submission handling via Server Actions that validates email input, checks for duplicates, creates the subscriber record in Turso, and redirects to a success message or optional downloadable asset.
```

5. **Workflow Automation Engine with Inngest** — Set up an asynchronous event-driven workflow engine using Inngest to handle multi-step automated email sequences with timed delays.

```
Integrate Inngest into the Next.js app to handle email automation workflows. Create an event listener for `subscriber.created` that triggers a multi-step workflow sequence. Build a workflow step definition interface where users can configure triggers, time delay steps (e.g., 'wait 2 days'), condition checks (e.g., 'did they click link X?'), and send email actions. Write the Inngest background function handler that executes these steps reliably, interacting with the Resend API to deliver scheduled emails.
```

6. **Campaign Broadcast & Resend Integration** — Connect the campaign scheduler to the Resend transactional email API to deliver newsletters to segmented audience lists.

```
Implement the campaign dispatch system. Build a campaign review screen where users select an email template, choose target subscriber segments or tags, and schedule or instantly broadcast the email. Write a server action that queries matching active subscribers from Turso, batches them in chunks, and sends them via the Resend API using the compiled HTML content and personalized merge tags (e.g., {{subscriber.email}}). Track delivery success and log campaign stats in the database.
```

7. **Stripe Checkout & Digital Product Sales** — Integrate Stripe Checkout sessions to enable creators to sell digital products and subscriptions directly inside the platform.

```
Implement e-commerce checkout support using Stripe. Create a products table in Turso and a UI for creators to set up digital product listings with price, title, and delivery file URL. Build an API route using Stripe Checkout SDK to create payment sessions. Set up a Stripe webhook handler endpoint that listens for `checkout.session.completed`, records the transaction, and automatically triggers an email via Resend containing the product download link to the buyer.
```
