LeadsBlue Email Deliverability Scorer

Honest, factor-based estimate of B2B email list deliverability (0-100) from verification, data age, jurisdiction, and industry.

Data source: LeadsBlue B2B Cold Email Benchmark Dataset · DOI 10.5281/zenodo.20136256

How it works

The score starts at 50 and adjusts for email verification, data age, the destination country's regulatory friction, and the industry's typical receptiveness (from benchmark open rates). It is an estimate, not a guarantee.
