Email verification
DeBounce 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 DeBounce or another provider on this list. DeBounce sells email verification. DeBounce sells email list cleaning and a validation API on pay-as-you-go credits, priced by the volume of checks.
Why people look beyond DeBounce
These are limits DeBounce states on its own pages.
- Add-ons cost more credits: catch-all checks use 10 credits each and data enrichment uses 20 per successful hit. Source
- List monitoring is billed at twice the list size each month. Source
Pricing model: Prepaid credits.
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.
