Cold Email & Deliverability Specialist | 2,500+ Meetings Booked

Hi, I'm Leo. I help B2B companies run cold email campaigns and manage deliverability health. This year, my campaigns have generated 2,500+ booked meetings, with a positive reply rate of 3.98-4.25% and an overall reply rate of around 2% in a highly competitive, high-volume vertical (business funding). ⚙️ Deliverability - ESP-segmented monitoring — Google vs. Microsoft, both on the sending and receiving side — because deliverability issues are almost always specific to one combination, not a blanket problem. - Clear criteria for when to retire a burned domain vs. repair it, tested with clean control emails to isolate whether the issue is reputation or copy. - Hands-on experience with providers like Reseller: I know what infrastructure works and what doesn't for the best results — not every provider performs the same depending on the destination ESP. ✍️ Copy & Personalization - Heavy spintax applied so every send reads as unique and avoids the repetitive patterns that trigger spam filters. - A/B testing built into every campaign from day one. 🤖 Automation - I automate operational and reporting tasks using Claude Code, freeing up time to focus on the work that actually moves campaigns forward. 📊 What you get - Weekly dashboards tracking the indicators that actually matter (replies, positive reply rate). - Fast reply triage: positives routed same-day, subsequences to re-engage warm leads that go quiet, opt-outs suppressed instantly and permanently. - Done-for-you execution or consulting to build this into your in-house team. Tools: Instantly, Claude Code. Infrastructure: Microsoft, Maildoso, Reseller, Koldify, Outreach Today. 💬 Testimonials "We started booking meetings from the first week. The process is clean, efficient, and unlike anything else in the market. It's allowed us to focus on closing rather than chasing leads." — Valentina Vega, Business Developer @ Guane Emerging Technologies
