I help businesses build reliable email systems for cold outreach, daily communication, and team operations.

I can handle cold email infrastructure, domain setup, mailbox setup, DNS, SPF, DKIM, DMARC, Google Workspace, Microsoft 365, email migration, deliverability fixes, Smartlead, Instantly, Clay, n8n, and Slack automation. My focus is clean setup, clear handoff, and fewer technical issues.
