Email verification
Kickbox 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 Kickbox or another provider on this list. Kickbox sells email verification. Kickbox sells email verification by prepaid volume tiers, from small packs up to one million verifications, with custom pricing above that.
Why people look beyond Kickbox
These are limits Kickbox states on its own pages.

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.
