Email verification
Clearout alternatives
LookValid does not offer a mailbox test. Its email domain check reads the domain behind an address and does not say whether one mailbox exists, so it is not ranked here. For that job, use Clearout or another provider on this list. Clearout sells email verification. Clearout sells email verification, an email finder and prospecting tools, paid through prepaid credits on monthly, annual or one-time plans.

Shortlist in email verification
Ranking rule: Lowest per-1,000 price in US dollars first, at the best volume tier the page prints. Where a page prints only a price per request, the per-1,000 figure is our arithmetic and is shown as "about". Providers with no dollar per-1,000 figure we can compare come after, and ties go by name.
