About this Gig

Are your emails landing in spam or being rejected by Gmail/Yahoo? Every blocked email is a lost sale and damages your brand.


As a Senior InfoSec Specialist with 10+ years protecting enterprise gateways, I will permanently fix your email deliverability and secure your domain against spoofing.


Enterprise-Grade Setup I Provide:


  • SPF: Correctly authorize all your sending sources (M365, Google Workspace, CRM, newsletters).
  • DKIM (DomainKeys Identified Mail): Implement cryptographic signatures to guarantee email integrity.
  • DMARC: Deploy strict policies (p=reject/quarantine) to stop cybercriminals from spoofing your domain.
  • MTA-STS & TLS-RPT: Enforce strict TLS encryption in transit and monitor inbound connection failures.
  • BIMI & DANE / DNSSEC: Display your official verified brand logo directly in the inbox and secure the DNS layer.


Platforms & Gateways Supported:


Google Workspace, M365/Exchange, AWS SES, Zoho, SendGrid, Mailchimp, cPanel, VPS and others.

I don't just add records; I audit your entire email routing flow to ensure zero legitimate emails are dropped
