The Email Authentication Audit That Added 16 Deliverability Points for Our Client

Before you touch subject lines, creative, or your offer — check your email authentication.

In this episode, Mark walks through the free 60-second deliverability check every Klaviyo brand should run: SPF, DKIM, DMARC via MX Toolbox, and your sending reputation in Google Postmaster.

You'll hear two real client results:→ Wavy: Klaviyo deliverability score up 11 points after fixing authentication→ Tallman Shoes: up 16 points, Google Postmaster spam rate below 0.03%

Plus the counterintuitive sending strategy that actually recovers deliverability — and why emailing more people when your reputation is down makes everything worse.

Creativity is downstream from deliverability. The best email in the world sitting in a spam folder is worth $0.
