Cold Email Expert Needed for Complete Email Audit, Remediation & ESP Migration

We're looking for an experienced cold email specialist to conduct a full audit of our current cold outreach infrastructure and lead a remediation and migration process. Our deliverability has been inconsistent, and we need an expert to diagnose the root causes and implement lasting fixes. The ideal candidate will assess our domain health, DNS records (SPF, DKIM, DMARC), sending reputation, and inbox placement rates, then provide a clear remediation plan. This includes cleaning up or rebuilding sending domains, warming up new infrastructure, and migrating us to a more reliable ESP suited for high-volume cold outreach. You should have proven experience with deliverability tools, domain/mailbox setup at scale, and ESP platforms commonly used for cold email (e.g., Instantly, Smartlead, or similar). Please share relevant case studies or past audit examples in your proposal. This is an opportunity for ongoing collaboration if the initial engagement goes well.
