I built a 7 figure cold email agency in 2 years. Here is everything I would do differently

Two years ago I started a cold email agency from my apartment with zero clients and a laptop. Hit 7 figures in annual revenue by month 22. Sounds great on paper. In reality, I burned through cash, lost clients I should have kept, and made infrastructure decisions that cost me months of progress. If I could rewind and start over, here is exactly what I would change.

Mistake 1: Starting on SMTP infrastructure. I spent my first 4 months on shared SMTP because it was cheap. $2 per inbox. What a deal, right? Except deliverability was terrible. Half my emails landed in spam. Clients churned because they were not getting results. I lost 3 of my first 5 clients before I figured out that the infrastructure was the problem, not my copy or targeting. If I started over, I would go straight to Google Workspace inboxes from PuzzleInbox on day one. The cost difference per inbox is nothing compared to the cost of losing clients.

Mistake 2: Undercharging. I started at $1,500/month per client because I was afraid nobody would pay more. At that price, I needed 20+ clients just to cover my costs and pay myself. The volume was unmanageable solo. I should have started at $3,000/month minimum and taken half the clients. Higher price attracts better clients who are more patient, more professional, and less likely to churn over one bad week. My current average client pays $3,800/month and the retention rate is significantly better than when I was charging $1,500.

Mistake 3: Hiring a salesperson before an ops person. My first hire was a closer to bring in more clients. Should have been an operations person to manage the infrastructure, data, and campaign setup. I was drowning in operations work while the salesperson brought in clients I could not properly service. Hire ops first. Then sales. In that order.

Mistake 4: Switching sending platforms twice. I started on Woodpecker, moved to Instantly, then settled on Smartlead. Each migration cost me about 2 weeks of downtime and confused clients. If I started over, I would go straight to Smartlead for the agency features. The white-label portals and unified master inbox are worth the price from client number one.

Mistake 5: Not specializing early enough. For the first year, I took any client in any industry. SaaS, real estate, recruiting, ecommerce, consulting. Each industry has different ICPs, different messaging, different compliance requirements. I was reinventing the wheel for every client. Once I narrowed to B2B SaaS and professional services, my copy templates became reusable, my targeting improved, and onboarding new clients went from 2 weeks to 3 days.

The numbers today: 28 active clients. Average revenue per client: $3,800/month. Monthly revenue: $106,400. Monthly costs: infrastructure ($2,100), tools ($890), two full-time ops staff ($9,200), data ($1,400), freelance copywriter ($3,000). Monthly profit before taxes: roughly $89,800. It took 22 months to get here, but the last 6 months have been consistently above $80K profit.

The biggest lesson: infrastructure and operations are the foundation. Copy and sales are important, but they do not matter if your emails land in spam or your operations are chaos. Get the boring stuff right first. The revenue follows.
