More signals, lower cost, credits that roll over indefinitely
Clearout charges calculator-based pricing on its site - check clearout.io/pricing for your volume. BounceZero charges $3 per 1,000 - a 66% reduction in cost per email for the same verification task. Credits never expire, so unused credits carry forward. No monthly subscription required.
Clearout uses domain + SMTP checking with catch-all detection. BounceZero adds a 5th stage: Bayesian + ML scoring trained on real delivery outcomes, catch-all 3-probe testing, social profile correlation, and domain reputation signals from 16 DNSBL sources. The extra depth reduces the "risky" bucket that Clearout returns for ambiguous addresses.
Clearout returns a status (Valid, Invalid, Catch-all, Unknown). BounceZero returns the same classification plus a confidence score (0-100) and a plain-English explanation that tells your team exactly why each address was classified - which signal triggered it, and what action to take. This is particularly useful for reviewing catch-all results and risky addresses before a campaign.
