The most valuable email metric that almost nobody tracks

More than half of your new leads may never see a single email you send. It’s not your subject line, offer or copy. It's something happening silently before your email ever reaches an inbox. In this episode of Data Beats Opinion, SegMetrics founder Keith Perhac talks with Adrian Savage, co-founder of EmailSmart and one of the sharpest minds in inbox visibility. They dig into why the open rate you're tracking is probably lying to you, the single most-overlooked engagement metric, and why blasting your entire list could be quietly wrecking the one marketing asset you actually own. If email is core to how you sell — and it should be — this episode will change how you read your own numbers.
