Outbound Deliverability & Campaign Diagnostic
Average cold email reply rates fell from 8.5% in 2019 to 3.43% in 2026 — but top-quartile campaigns still hit 5.5%+ and elite campaigns clear 10.7%. This checks your actual campaign against the specific, named reasons that separate the two.
Benchmarks and failure signatures sourced from Instantly's 2026 Cold Email Benchmark Report and Orum's 2026 State of Sales Development. Nothing you enter here is uploaded — this runs in your browser only.
