About this gig

Most cold email campaigns fail before the first email is read. Wrong authentication, no warmup, no list validation. The campaign fails at the infrastructure layer not the copy or the offer.


I build complete cold email systems using the Infrastructure-First Method which means deliverability is verified before a single campaign email goes out.


What I build: Dedicated sending domains purchased and configured fully separated from your main domain SPF, DKIM, DMARC set up and verified on MxToolbox before warmup starts Instantly account configured warmup running, sending limits calibrated to your volume Apollo ICP filters built role, company size, industry, funding stage, hiring signals NeverBounce list validation bounce rates below 1% before import 3-step email sequence loaded in Instantly A/B testing enabled, reply detection configured Deliverability test sends confirming inbox placement in Gmail and Outlook before launch


What you receive: Live campaign ready to activate not left in draft Clean verified lead list matching your ICP MxToolbox results showing all authentication passing Loom walkthrough video showing you how to monitor and manage the system Written handover doc
