Email Deliverability Specialist for Existing Cold Email System

Hello there, I am looking for an email deliverability specialist to help me review, maintain, and improve an existing cold email setup. I already have a cold email system in place, with sending domains, email accounts, DNS records, and campaigns already configured. I would like someone technical to help me make sure everything is properly set up and performing as well as possible from a deliverability perspective. I am mainly looking for help with: - Reviewing DNS/email authentication setup - Checking SPF, DKIM, DMARC and related records - Reviewing sending domains, tracking domains, and unsubscribe setup - Running deliverability tests and explaining the results clearly - Identifying any technical issues that may hurt inbox placement - Suggesting safe improvements without disrupting the current system - Helping me maintain the setup as campaigns continue This is not a copywriting role. I am looking for someone with strong technical experience in email deliverability and cold email infrastructure. Experience with cold email tools, SMTP, DNS, mail-tester, GlockApps, Instantly or similar platforms would be very helpful. Please include a short note about your experience with email deliverability and how you usually approach reviewing an existing cold email system. Thank you.
