DNS Architecture & Deliverability

Authoritative DNS management and email authentication (SPF, DKIM, DMARC) to ensure your infrastructure is trusted globally.

Technical Execution

Core deliverables associated with this capability.

Email Authentication Alignment

Strict configuration of SPF, DKIM, and DMARC records to satisfy Google and Yahoo sender requirements.

DNS Zone Remediation

Cleaning up conflicting A, AAAA, and CNAME records, and resolving propagation delays.

Platform Integration

Connecting domains seamlessly to Google Workspace, Microsoft 365, Zoho, or third-party CRMs.

Zero-Downtime Domain Cutovers

Coordinating registrar changes, nameserver updates, and TTL lowering for seamless launches.

Common Scenarios

Typical infrastructure and codebase challenges I resolve.

  • Your transactional emails (receipts, password resets) are landing in spam.
  • You are receiving DMARC failure reports and do not know how to read them.
  • You need to change nameservers to Cloudflare without breaking your existing Office 365 emails.
  • Your domain is blacklisted due to a previous configuration error.

Measurable Outcomes

  • Near 100% inbox placement for authenticated email channels
  • Elimination of DNS-related downtime during website launches
  • A clean, documented zone file that your IT team can easily manage

Technical FAQ

Why are my emails going to spam if I am not a spammer?

Modern inbox providers require strict cryptographic proof (DKIM) and policy alignment (DMARC). Without these, your domain looks identical to a forged sender.

How long does a DNS fix take to work?

Depending on the previous TTL (Time to Live) settings, DNS propagation can take anywhere from 5 minutes to 48 hours globally.
