Email Deliverability & Infrastructure | Email Security Expert

Email deliverability consultant with 10+ years in the field and worked with 500+ clients. If your emails are landing in spam, your domain reputation is damaged, your domain is being spoofed, or your cold email campaigns have stopped delivering, I fix that. I work with SaaS companies, agencies and high volume senders on four things: deliverability, email security, cold email infrastructure, and large scale sending systems. WHAT I FIX ✓ Emails landing in spam or Promotions instead of the inbox ✓ Damaged domain and IP reputation ✓ SPF, DKIM, DMARC and BIMI that is misconfigured or failing alignment ✓ Domains being spoofed, and inboxes exposed to phishing and BEC ✓ Cold email setups that burn domains instead of booking meetings ✓ Sending systems that cannot scale past their current volume ✓ Bounce, complaint and feedback loop handling that nobody owns ✓ Develop your inhouse tools for email marketing, email deliverability monitoring and email security RESULTS • Clients sending 50M+ emails per month safely • Spam and deliverability issues resolved for 200+ businesses • $400K+ earned on Upwork at 100% Job Success • Infrastructure built on SES, SendGrid, Mailgun, PowerMTA, GreenArrow and MailerQ SERVICES AND PRICING 1. Email Deliverability Audit ($1,000 to $5,000) SPF, DKIM, DMARC and alignment analysis. Google Postmaster and Microsoft SNDS review. Seed and spam placement testing. Domain and IP reputation analysis. Written report with prioritised fixes, plus a walkthrough call. 2. Cold Email Infrastructure Setup ($1,500 to $5,000) Domain and mailbox architecture, authentication, warm up strategy and execution, Smartlead / Instantly / Apollo configuration, sending limits and ramp schedule. 3. High Volume Sending System Build ($2,000 to $8,000) Amazon SES, SMTP or PowerMTA configuration, authentication, IP warming, bounce and complaint handling, feedback loop integration, monitoring. 4. Email Security Hardening DMARC enforcement from p=none to p=reject, anti spoofing, BIMI and VMC implementation, MTA-STS and TLS-RPT. WHY ME RATHER THAN SOMEONE CHEAPER I build the tools I use. My free public tools cover DNS and authentication lookups, blacklist checks, domain spoofability grading, mail testing, and DMARC, TLS-RPT and inbox placement monitoring. I publish technical guides and track standards changes. When a mailbox provider changes the rules, I already know. PLATFORMS Infrastructure: Amazon SES, SendGrid, Mailgun, PowerMTA, Postfix, GreenArrow, MailerQ, EmailSuccess Cold email: Smartlead, Instantly, Gmass, Apollo, Clay, GoHighLevel, Mailshake, Klenty, SalesHandy, Snov Marketing: Klaviyo, Iterable, Braze, AWeber, GetResponse, Zoho Mailbox providers: Google Workspace, Microsoft 365 Monitoring and testing: Google Postmaster Tools, Microsoft SNDS, GlockApps, Validity Everest, Litmus, Email on Acid, Mail-Tester HONEST EXPECTATIONS Deliverability is a process, not a one-time fix. Inbox placement depends on authentication, infrastructure, list quality, content and recipient engagement, and I only control some of those. I am a technician, not a magician. If someone promises you guaranteed inbox placement, they are selling you something. TO GET STARTED Message me with your sending domain, your current platform, your monthly volume, and what you are seeing (spam placement, bounces, a specific error, a Postmaster screenshot). I will tell you what is wrong and what you need.
