Build guide

1. 01Project Scaffolding & Database Schema

   Initialize the Next.js application, configure Turso SQLite connection, setup better-auth, and define tables for leads, campaigns, sequences, and CRM deals.

   Scaffold a new Next.js 16 project using TypeScript, Tailwind CSS, and App Router. Integrate Turso database connectivity using the libSQL client. Implement better-auth with email/password authentication. Create database migration scripts for the following relational tables: 'leads' (id, email, first_name, last_name, company, phone, status), 'campaigns' (id, name, status, user_id), 'sequence_steps' (id, campaign_id, step_order, delay_days, template_subject, template_body), and 'crm_deals' (id, title, stage, value, lead_id, created_at). Ensure all foreign keys and indexes are properly structured for fast querying. Provide a clean layout shell with sidebar navigation using shadcn/ui components.

2. 02Lead Management & Domain Search UI

   Build the lead discovery interface, CSV import parser, and company domain lookup tool.

   Build a lead management dashboard page in Next.js with a searchable, sortable data table displaying leads from the database. Implement a CSV import modal that parses uploaded lead files, validates email structures using regex, and batch-inserts records into the 'leads' table. Add a domain search input box that triggers a backend route to query company domain patterns (e.g., guessing common corporate email structures like firstname.lastname@domain.com) and saves discovered contacts to the active list.

3. 03Email Verification Engine

   Implement a multi-tier email verification checker including syntax, MX record lookup, and SMTP handshake testing.

   Create an email verification service module in Node.js that executes a 3-tier verification check on any provided email address: 1) Syntactic validation via regex and disposable domain check, 2) DNS lookup to verify MX records for the target domain, and 3) A lightweight SMTP handshake connection (RCPT TO command simulation without sending an actual message) to test mailbox existence and avoid greylisting false positives. Expose an API endpoint /api/verify that returns structured verification status codes and bounce risk ratings.

4. 04Outreach Campaign Drip Engine

   Develop the automated drip campaign runner with sequencing rules, delay scheduling, and spintax personalization.

   Implement the drip campaign orchestration engine. Create an API route for launching and pausing campaigns. Build a background cron worker script (designed to run via Fly.io) that queries active campaign steps, evaluates scheduling delays, processes spintax variations in email subjects and bodies (e.g., '{Hello|Hi|Dear} {FirstName}'), and dispatches emails using the Resend API. Log each sent message in a 'campaign_sends' table and update recipient status accordingly.

5. 05Unified Inbox (Unibox) & CRM Pipeline

   Build the shared inbox view for tracking replies and the Kanban board CRM for pipeline management.

   Build a unified inbox component ('Unibox') that aggregates inbound email replies and outbound message threads into chronological conversation views. Implement an IMAP listener worker that polls connected mailboxes for incoming replies and links them to the correct lead and campaign. Additionally, build a drag-and-drop or column-based Sales CRM Kanban board using shadcn/ui where deals can be moved across customizable pipeline stages (Lead, Contacted, Meeting Booked, Closed Won, Closed Lost) linked directly to lead profiles.
