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

> Email marketing software you'll actually enjoy using.

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

## Verdict

You can build a functional personal clone of the editor, subscriber CRM, and basic automation engine, but keeping out of spam folders and building multi-user CRDT sync will test your persistence.

The core loop of drafting emails in a block editor, storing contacts in Postgres, and triggering simple sequences is entirely achievable with AI coding tools. However, email deliverability is a minefield; if you try to spin up your own SMTP server from scratch without routing through an established provider like Mailgun or Amazon SES, your test emails will land permanently in Gmail spam. Furthermore, building a robust visual workflow engine for drip sequences requires writing a resilient background job queue that handles time-based delays without dropping state during server restarts.

### What you can't replicate

- Established IP reputation and inbox placement history with Gmail, Outlook, and Yahoo
- Production-grade compliance vetting for automated spam monitoring across thousands of domains

## What it does

An all-in-one email marketing, automation, and transactional email platform with a Notion-style collaborative writing workspace and AI agents.

### Core features

- Notion-style collaborative rich-text editor with slash commands and blocks
- Real-time multi-user editing with live presence and cursors
- Visual marketing automation workflow builder (drip sequences, delays, conditionals)
- Subscriber list management with tags, custom fields, and dynamic segmentation
- Email dispatch engine with domain authentication (SPF, DKIM, DMARC)
- Transactional email API and SMTP server relay
- AI assistant integration for drafting campaigns, newsletters, and sequences
- Analytics reporting engine for opens, clicks, unsubscribes, and delivery rates
- Embeddable signup forms and lead-magnet capture pages

## The business

### Pricing

- Free Tier: $0 / mo
- Essentials Plan: $29 / mo
- Growth Plan: $56 / mo
- Enterprise Plan: Custom

Founded 2020.
Team size: Small bootstrapped team.

## The hard parts

- Maintaining high email deliverability, handling bounce feedback loops, and preventing spam complaints without ruining sender reputation
- Building a bulletproof state machine for automated visual journeys that correctly evaluates time-based delays ('Wait 2 days') and branching conditions
- Implementing real-time multi-user document editing with live cursors and conflict resolution
- Ingesting high-throughput webhook events and transactional API requests reliably under load

## How to vibe code Audienceful

### Prerequisites

- Node.js (free): Runtime environment for running the full-stack Next.js application.
- GitHub (free): Version control repository and CI/CD deployment pipeline hook.
- Mailgun or Resend Account (free tier available): Mandatory underlying email sending infrastructure to ensure domain authentication (SPF/DKIM) and actual inbox placement.

### Recommended AI tools

- Claude Code: Unmatched ability to scaffold multi-file database schemas, API routes, and complex frontend block editors autonomously from detailed prompts.
- Cursor: Ideal for fine-tuning the Notion-style rich text editor UI components, drag-and-drop blocks, and visual workflow canvas nodes with instant visual diff reviews.

### Stack

- Frontend: Next.js with Tailwind CSS and Tiptap / BlockNote rich text editor
- Backend: Next.js Server Actions and API Routes
- Database: Neon (Serverless Postgres)
- Auth: better-auth
- Payments: Stripe (optional for billing integration simulation)
- Other: Liveblocks for real-time multiplayer cursors and collaborative editing, Inngest for durable background workflow automation and timed delay steps, Resend for transactional and campaign email dispatch

### Hosting

- Vercel (Hosting the Next.js frontend and serverless API functions): $0-20/mo
- Neon (Managed serverless Postgres database for subscribers and campaigns): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project with Tailwind CSS, configure better-auth for workspace user management, and set up the Neon Postgres schema for subscribers, tags, campaigns, and automations.

```
Scaffold a new Next.js application with TypeScript, Tailwind CSS, and App Router. Set up Drizzle ORM connected to Neon Postgres. Create database tables for users, workspaces, subscribers (email, name, status, custom_fields, unsubscribed_at), tags, subscriber_tags (many-to-many), campaigns (title, subject, content_json, html_body, status, scheduled_at), and automated_journeys. Implement better-auth with email/password and workspace organization plugins. Ensure all database relations and foreign keys are cleanly configured with proper indexes on subscriber emails and campaign IDs.
```

2. **Notion-Style Collaborative Rich-Text Editor** — Build the campaign composition interface using a block-based editor framework integrated with Liveblocks for real-time multi-user presence and live cursors.

```
Build a campaign creation and editing page in Next.js featuring a block-based rich text editor (using Tiptap or BlockNote) that mimics Notion. Implement slash commands (/heading, /image, /button, /divider) and per-block styling controls. Integrate Liveblocks to enable real-time multi-user collaboration with live cursors, active collaborator avatars in the header, and inline comments. Add a preview toggle that compiles the block JSON document into clean, mobile-responsive HTML suitable for email clients, complete with dark-mode variable support.
```

3. **Subscriber CRM, Segments & CSV Import** — Implement the audience management dashboard, tag assignment system, dynamic filtering, and CSV contact list importer with error handling.

```
Create an Audience CRM dashboard page that lists subscribers with pagination, search, status filters (active, bounced, unsubscribed), and tag filters. Build a CSV import wizard that parses uploaded contact sheets, maps columns to custom fields, checks for duplicate emails, and bulk-inserts records into Neon Postgres while assigning selected tags. Implement dynamic segmentation rules where users can save segment filters based on tags and custom field criteria for targeted email blasts.
```

4. **Visual Marketing Automation Workflow Engine** — Develop a visual node-based drip sequence builder backed by Inngest durable background jobs to handle triggers, time delays, and branching logic.

```
Build a visual workflow automation builder interface where users can design drip sequences. A sequence starts with a trigger node (e.g., 'New subscriber added' or 'Tag added'), followed by action nodes ('Send email') and delay nodes ('Wait 2 days' or 'Wait 4 hours'). Implement backend execution using Inngest step functions to handle durable background execution, ensuring timed delays wait reliably without timing out serverless execution limits. Handle state persistence so subscribers progress through steps accurately and can exit upon conversion or unsubscription.
```

5. **Email Sending Pipeline & Domain Authentication** — Connect the campaign dispatcher and transactional endpoints to Resend/Mailgun, tracking open/click webhooks and delivery metrics.

```
Implement the email dispatch engine using the Resend API SDK. Create backend API routes to process bulk campaign sends against targeted subscriber segments, personalizing merge tags (e.g., {{subscriber.name}}) before dispatch. Set up webhook ingestion endpoints to receive delivery, open, click, bounce, and complaint events from the email provider, updating campaign analytics counters and automatically marking hard-bounced or unsubscribed emails in the database to protect sender reputation.
```

6. **AI Assistant Integration & Final Polish** — Integrate Anthropic or OpenAI API endpoints to generate campaign copy and outline automated sequences directly from a chat prompt drawer.

```
Add an AI assistant slide-over drawer to the campaign editor powered by the Anthropic API. Allow users to prompt the AI to draft newsletters or subject lines matching a specified brand voice. Include confirmation previews so users can inspect generated blocks before inserting them into the editor document. Polish the application dashboard with summary metrics cards (total subscribers, average open rate, delivery health) and comprehensive error boundaries.
```
