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

- Verdict: **Solid side project** (68/100 vibecodeable)
- Estimated effort: 3-4 weeks of focused development

## Verdict

You can build a functional personal email cleaning dashboard, but dealing with IMAP connection stability and OAuth quirks across providers will consume most of your build time.

Building a personal-use clone of Clean Email requires writing robust IMAP/OAuth connectors and setting up background worker queues to fetch metadata without freezing the UI. While an AI agent can scaffold the Next.js frontend, database schema, and basic parsing heuristics quickly, handling provider-specific rate limits, token refreshes, and connection drops across Gmail, Microsoft, and IMAP will test your patience. Because Clean Email costs around $10-20/mo, building this is strictly a fun or privacy-motivated project rather than a financial shortcut.

### What you can't replicate

- 10 years of edge-case bug fixes across thousands of weird mail server implementations
- Enterprise security audits and third-party privacy certifications

## What it does

A cloud-backed service that connects to mail accounts via IMAP/OAuth2 to provide smart folders, bulk unsubscribing, automated cleaning rules, and sender screening.

### Core features

- Secure IMAP and OAuth2 connection management (Gmail, Outlook, iCloud, Custom)
- Metadata-only indexing (headers, subjects, dates, senders without downloading body/attachments)
- Smart folder grouping and cleaning suggestions (social, old mail, marketing)
- Bulk Unsubscriber (sending unsubscribe requests and blocking stubborn mailing lists)
- Auto Clean background rule engine (scheduled/event-driven actions on incoming mail)
- Screener inbox bouncer for unknown senders

## The business

### Pricing

- 1 Account: $9.99/mo
- 5 Accounts: $19.99/mo
- 10 Accounts: $29.99/mo

Founded 2014.
Team size: ~14-23.

## The hard parts

- Maintaining stable, persistent IMAP connections across multiple email providers without hitting rate limits or lockouts
- Secure credential storage and handling of provider OAuth tokens and app-specific passwords
- Efficient background pagination and incremental syncing for mailboxes with tens of thousands of messages
- Parsing erratic RFC-5322 email headers, List-Unsubscribe headers, and unstructured body footers reliably

## How to vibe code Clean Email

### Prerequisites

- Node.js (free): Required runtime for running Next.js and backend worker services.
- GitHub (free): Source code control and deployment pipeline integration.

### Recommended AI tools

- Claude Code: Agentic coding tool for scaffolding IMAP connection handlers, database models, and React UI components.
- Cursor: Ideal for fine-tuning complex React UI dashboard components and sorting views.

### Stack

- Frontend: Next.js with Tailwind CSS and shadcn/ui
- Backend: Next.js API Routes + Background Worker (Node.js/BullMQ or Inngest)
- Database: Turso (SQLite at the edge for account settings, rules, and cached message metadata)
- Auth: better-auth
- Payments: none
- Other: node-imap / imapflow for mail server connection, Upstash Redis for background job queue backing

### Hosting

- Vercel (Hosting the Next.js frontend and serverless API endpoints): $0/mo
- Railway (Running persistent background worker processes for IMAP sync and cron rules): ~$5/mo
- Turso (Lightweight SQLite database for storing user accounts, encrypted credentials, and cached email metadata): $0/mo

### Build guide

1. **Project Scaffolding and Database Schema** — Initialize the Next.js project with Tailwind CSS, shadcn/ui, and better-auth. Set up Turso database schema for users, connected mail accounts, sync logs, auto-clean rules, and cached email metadata headers.

```
Scaffold a Next.js 16 application with TypeScript, Tailwind CSS, and better-auth. Set up a Turso database schema using Drizzle ORM containing tables for: users, accounts (storing encrypted IMAP credentials/tokens, provider type, email address), cached_messages (id, account_id, message_id, subject, sender, date, size, flags, folder), auto_clean_rules (id, account_id, criteria, action), and unsubscribe_logs. Provide a clean project layout with a dashboard layout shell.
```

2. **OAuth2 and IMAP Credential Integration** — Implement authentication and secure credential storage for external mail accounts, including Google OAuth2 configuration and custom IMAP / app-specific password connections with encrypted token handling.

```
Build account connection flows in Next.js supporting Google OAuth2 and generic IMAP (server, port, username, password/app-specific password). Implement AES encryption helpers to store credentials securely in the database. Ensure tokens and passwords are never exposed to the frontend and are decrypted only within secure server actions or background worker jobs.
```

3. **IMAP Synchronization Engine** — Build a background syncing service using imapflow or node-imap to fetch message headers (subject, sender, date, flags, size) without downloading body content or attachments, storing metadata incrementally in Turso.

```
Implement an IMAP synchronization worker using `imapflow` that connects to a user's mail provider, lists mailboxes, and fetches message headers (Message-ID, Subject, From, Date, Size, Flags) for the INBOX and recent folders. Ensure it processes messages in pages, handles connection drops with exponential backoff, and saves metadata into the cached_messages table without ever downloading email bodies or attachments.
```

4. **Smart Folders and Cleaning Suggestions** — Create heuristic grouping algorithms to categorize cached email headers into smart bundles such as Social Networks, Old Emails, and Marketing Blasts, displaying them in a unified dashboard.

```
Build React dashboard views in Next.js that group cached message metadata into Smart Folders and Cleaning Suggestions using heuristic filters (e.g., matching common social domain patterns, messages older than 6 months, or high-frequency marketing senders). Include bulk selection checkboxes and action buttons for archive, delete, and move.
```

5. **Bulk Unsubscriber and Header Parser** — Parse RFC-5322 List-Unsubscribe headers from message metadata to consolidate newsletter subscriptions into a single management view with one-click bulk unsubscribe capability.

```
Implement an Unsubscriber feature that extracts List-Unsubscribe headers and mailto/http links from cached message headers. Create an interface listing all active newsletter subscriptions grouped by sender, with buttons to trigger bulk unsubscribe requests (sending a mailto or hitting the unsubscribe URL) and options to block or read later.
```

6. **Auto Clean Background Rules Engine** — Implement a background rules engine and scheduler that automatically evaluates incoming message headers against user-defined Auto Clean rules (e.g., auto-archive social alerts) and executes IMAP flag updates.

```
Build an Auto Clean rule management UI and a background job worker (using Inngest or Railway cron) that periodically evaluates newly synced message headers against user rules. When a match occurs, execute the corresponding IMAP action (e.g., add 
Deleted flag, move to archive folder) and log the automated action to the database.
```

### Cost vs paying

**Starting costs (one-time):**
