The Cold Outreach Blueprint

A complete cold outreach system built on the infrastructure and tactics of @dimitarangg, who generated $100K in 60 days using an n8n cold email automation, replaced three human setters with a $20/month Claude Code subscription, and sold a productized cold outreach system for $7K plus 20% revenue share on every dollar it generates.

B2B Lead Generation is growing at 3,307% in engagement across the dataset of 105,261 tweets from 244 accounts. The demand for automated outreach systems is accelerating faster than almost any other category. This is the exact infrastructure to capture that demand.

Part 1: Domain and Email Infrastructure

This is the foundation. Get this wrong and nothing else matters. Your emails go to spam and you burn through domains.

Domain Setup

Buy 5 sending domains. Not your main business domain. Never send cold email from your primary domain. If a sending domain gets flagged, you burn it and spin up a new one. Your main domain stays clean.

Domain naming convention:

• yourbrand-team.com
• getyourbrand.com
• tryyourbrand.com
• yourbrandmail.com
• yourbrand-hq.com

Keep them close enough to your brand to appear legitimate, but separate enough to protect your main domain's reputation.

Purchase from: Namecheap, Google Domains, or Cloudflare. Cost: $10-15 per domain per year.

DNS configuration for each domain: 1. SPF record: v=spf1 include:outlook.com ~all (adjust for your email provider) 2. DKIM: generate through your email provider and add the TXT record 3. DMARC: v=DMARC1; p=none; rua=mailto:dmarc@yourbrand.com

These three records tell receiving mail servers that your emails are legitimate. Without them, you go straight to spam.

Email Infrastructure

@dimitarangg specifically uses Outlook domains. Not Gmail. Not custom SMTP. Microsoft Outlook.

Why Outlook: Higher deliverability to corporate inboxes (most B2B prospects use Outlook/Exchange), less aggressive spam filtering on outbound, and Microsoft domains carry inherent trust.

Setup per domain:

• Create 3 email accounts per domain (e.g., alex@, sarah@, mike@)
• 5 domains x 3 accounts = 15 sending accounts
• Each account sends maximum 30 emails per day
• 15 accounts x 30 emails = 450 emails per day capacity

Warmup period: New email accounts must be warmed before sending cold email. Use a warmup tool (Warmbox, Lemwarm, or Instantly's built-in warmer) for 14 days minimum. The tool sends and receives emails between your accounts and a network of other accounts, building your sender reputation with email providers.

Warmup settings:

• Start at 5 emails/day
• Increase by 3 every 2 days
• Target: 30 emails/day after 14 days
• Keep warmup running even after you start sending cold email (reduces to 10-15/day alongside your cold sends)

Cost Summary: Infrastructure

• 5 domains: $60/year
• 15 Outlook accounts: ~$90/month (Microsoft 365 Business Basic at $6/user/month)
• Warmup tool: $30-50/month
• Total infrastructure: ~$140/month

Part 2: Lead Sourcing

Your list is everything. A perfect email to the wrong person is worthless. A decent email to the right person is money.

Primary Sources

LinkedIn Sales Navigator ($80/month) The single best B2B lead sourcing tool. Search by:

• Industry
• Company size (employee count)
• Title/role
• Location
• Company growth signals (hiring, funding, recent news)

Apollo.io (free tier available, $49/month for full features) Email finder + enrichment. Plug in a LinkedIn profile or company, get verified email addresses. Apollo's database covers 250M+ contacts.

Crunchbase (for funded companies, $29/month) Search by funding round, industry, and size. Recently funded companies have money to spend and problems to solve. They're the ideal cold outreach targets.

The Targeting Framework

@dimitarangg's automation was "stalking 341 LinkedIn profiles, analyzing behavioral psychology" per prospect. You don't need to match that sophistication on day one, but you do need targeting criteria.

Ideal Customer Profile (ICP) for selling AI/automation services:

• Company size: 10-100 employees (big enough to have budget, small enough to not have an internal solution)
• Industry: ecommerce, SaaS, marketing agencies, real estate, recruiting
• Recent signals: just raised funding, recently hired for a role your service replaces, posted about a pain point on LinkedIn
• Decision maker title: Founder, CEO, Head of Marketing, VP Operations

List building workflow: 1. Search Sales Navigator with ICP criteria 2. Export to Apollo for email enrichment 3. Verify emails through a verification service (NeverBounce, ZeroBounce: $0.003/email) 4. Import verified list into your sending tool

Target: 200+ verified leads per week

Part 3: AI-Powered Personalization

This is where Claude Code replaces the human work. @dimitarangg replaced 3 setters with a $20/month Claude Code subscription. The math: $20/month v
