Can I vibecode Mailcoach Cloud?

Build a privacy-first, self-hostable email marketing and newsletter platform inspired by Mailcoach Cloud.
Use Next.js 14 App Router, TypeScript, TailwindCSS, and PostgreSQL with Prisma ORM.

### Data Model
- `List`: id, name, default_from_email, default_from_name, require_double_opt_in.
- `Subscriber`: id, list_id, email, first_name, last_name, status (unconfirmed, subscribed, unsubscribed, bounced), created_at.
- `Campaign`: id, list_id, subject, html_content, status (draft, scheduled, sending, sent), scheduled_for.
- `Template`: id, name, html_content.
- `SendLog`: id, campaign_id, subscriber_id, status (sent, bounced, complained), created_at.

### Screens & UX Patterns
1. **Audience Dashboard**: A metrics-heavy view showing total subscribers, list growth over time (line chart), and a paginated data table of recent subscribers with bulk action checkboxes (delete, unsubscribe).
2. **Campaign Builder**: A multi-step wizard. Step 1: Campaign details (subject, from name). Step 2: HTML email editor (a rich text editor block that outputs clean, inline-styled HTML). Step 3: Audience selection and scheduling. Step 4: Review and send.
3. **Subscriber Profile**: A detailed drawer or page for a single subscriber showing their timeline of received emails, opens/clicks, and subscription status.
4. **Settings & Integrations**: A form to input API keys for standard SES/Mailgun/Postmark providers and Webhook URLs to receive bounce/complaint data.

### Step-by-Step User Journey
1. **List Setup**: User creates a "Weekly Newsletter" list and uploads a CSV of 500 existing subscribers.
2. **Drafting a Campaign**: User selects the "Newsletter" template, drops in text and images, and previews the email to ensure it renders correctly across devices.
3. **Sending via SES**: User schedules the campaign. A background job (e.g., using BullMQ or Inngest) chunks the subscribers into batches of 50 and dispatches them via the configured Amazon SES API.
4. **Handling Feedback Loop**: A subscriber's mailbox is full (hard bounce). Amazon SES hits the app's Webhook endpoint `/api/webhooks/ses`. The app updates the `Subscriber` status to "bounced" to protect sender reputation.

### Technical Specifics
- Use a robust background job queue (like BullMQ + Redis) for the sending engine to handle large lists without timing out the web server.
- Implement rate-limiting logic in the sending queue to respect AWS SES or Mailgun API quotas (e.g., 14 emails/second).
- Parse multipart/form-data for CSV uploads and validate email addresses via Regex and DNS MX record checks before saving.
- Include an API route to handle incoming webhooks for bounces and complaints from major ESPs, securely validated via signature headers.
