About TechDenX

TechDenX provides a focused, proof-based setup service for email authentication and bulk-sender compliance basics. The goal is simple: make sure your domain is configured correctly (SPF/DKIM/DMARC) and that your marketing mail meets unsubscribe expectations where applicable.

This is a narrow, implementation-first sprint — not ongoing deliverability consulting. You get objective pass/fail verification and clean documentation you can keep.

• Fast turnaround: 48 hours after access
• Objective results: pass/fail checks with proof
• Clear boundaries: legitimate senders only
• No passwords required; DNS access preferred
