Building a Cold Email Machine: Results and Proven Strategy

✉️Sent 79,500 emails. 📬Got 6,916 replies. 👥Generated 759 leads 📆Booked 348 meetings. 💰Closed 68 high ticket deals All cold. All automated. All for our own company over a 7 months period. This is how I built an evergreen cold email machine that runs 24/7 and delivers real results every single week - without touching a single inbox manually. The System Behind the Numbers: Most people obsess over vanity metrics like open rates or clicks. I don’t track either. I only care about replies and revenue. The system is built on 3 core pillars: ✉️ DELIVERABILITY - Inbox placement is the foundation. Here’s exactly how I engineered it:

Bought a high volume of mailboxes through Maildoso
Connected all inboxes to instantly
Warmed them up for 3 weeks before sending
Sent 7 emails per day per inbox
Sent 60 warm-up emails per inbox per day
No tracking domain used
No links in any emails
No spam words
Used spintags heavily - even on the signature
Signature = just my first name
Minimum 90-minute send delay between emails
Rotated copy every 2 weeks to avoid ESP detection
Redirected domains to my main brand site to generate organic traffic
Never tracked opens or clicks - just replies and conversions

🧲 LEAD LIST - The copy means nothing if it’s sent to the wrong people. Here’s how I sourced intent-based, high-fit leads:

Identified 100+ competitors in the lead gen space
Used PhantomBuster to scrape every post they made over the past 3 months
Extracted everyone who liked or commented on those posts
Imported raw data into Clay for filtering and enrichment
Applied filters for: company size, job title, location, etc.
Enriched leads by: normalizing company name, finding the website, etc, etc.
Double-verified emails to keep bounce rate under 2%

It left me with a clean, verified, intent-rich list of prospects that already engage with similar offers. ✍️ COPYWRITING - Every email felt personal, because it was. I built AI workflows that made 1:1 personalization scalable:

Researched recent wins or milestones at their company
Referenced that event at the top of the email
Tied it directly to one pain and one clear outcome
Wrote in a casual, natural tone - like I speak
Every email had:
All generated by AI, guided by strict formatting rules and spintax

And by all of this, I get deals while I sleep. If you’re trying to build a cold email engine that actually books meetings and closes clients - I’m happy to help you built one. This is a system that can be used for every kind of industry out there.
