Technical systems behind deliverability, outbound performance, and scalable outreach campaigns.
Inbox placement audits, SPF/DKIM/DMARC configuration, domain reputation troubleshooting, and deliverability monitoring across Google Workspace, Microsoft 365, and outbound email platforms.
Outbound systems built for scalable cold email campaigns, including sending domains, inbox provisioning, DNS setup, tracking domains, and platform configuration across Apollo, GoHighLevel, and Instantly.
Editorial outreach and digital PR campaigns focused on earning relevant placements, building publisher relationships, and improving long-term search visibility through authority-driven links.
Sherman Digital Co. focuses on the systems behind outbound performance. What started in SEO outreach and digital PR evolved into deeper work around email deliverability, outbound infrastructure, domain reputation, and campaign operations.
Many outreach and cold email campaigns fail long before the copy is ever read. The issue is often hidden inside the infrastructure itself. Misconfigured SPF, DKIM, and DMARC records, damaged sender reputation, poor sending behavior, disconnected workflows, and outreach systems that were never built to scale.
Today, the focus is on building and stabilizing the technical foundation behind outbound campaigns. That includes email deliverability audits, cold email infrastructure, Google Workspace and Microsoft 365 troubleshooting, domain reputation recovery, prospecting systems, and outreach operations designed for long-term performance.
