How we review
We do not guess. We run the test, then publish.
Every verdict on this site traces back to a campaign we actually ran or a list we actually verified. Here are the numbers, with the full method inside each report.
Hunter.io verifier accuracy across five industries, from 88 to 96 percent, and the reason the gap is that wide.
A 41 percent open rate, 6.2 percent reply and 3.8 percent bounce over six weeks, with the full campaign breakdown.
We pushed 10,000 cold emails through a single Gmail account to find where the suspension line actually sits.
Twelve straight weeks of inbox versus spam placement, logged provider by provider instead of guessed at.
Hunter.io and Snov.io run on the same list, which opened a 43 point accuracy gap once we split it by segment.
Five hundred LinkedIn profiles run through the Chrome extension, and a clear picture of what it finds and what it misses.
