Email Deliverability Expert | DNS, DMARC, SPF/DKIM, GoHighLevel
Are you an agency owner running high-volume cold outreach, only to watch response rates drop because your emails are landing in spam? I fix that by rebuilding the infrastructure underneath it: DNS authentication, IP reputation, and sending architecture built to survive the 2024-2026 Google and Yahoo updates that broke most basic cold email setups. A few recent results. Took a client's domain health score from 2/10 to a perfect 10/10. Rebuilt a fintech company's infrastructure to hit 100% primary inbox placement via a dedicated VPS. Migrated a business to Google Workspace with zero downtime and hardened DNS security. What I actually do: SPF, DKIM, and DMARC alignment done right the first time. Multi-domain sending architecture built for scale. Mailbox warm-up sequencing. Ongoing monitoring for blacklists and reputation drops, so problems get caught before they cost you leads. I'm currently completing a Master's in Network Engineering and Information Systems, which is exactly the technical background this work draws on. If your outbound is stuck in spam, or you're scaling past what your current setup can safely handle, let's talk about what's happening with your sending infrastructure.
