Comparisons
Each page puts the terms side by side: price at your volume, credit expiry and whether unknowns are billed. It also shows what each accuracy figure is measured against.
Prices come from each vendor's own pricing page, dated September 2026. Where a vendor gates pricing behind a form or blocked our checks, the page says so instead of showing a number we could not confirm.
What ZapBounce brings to every comparison is on its pricing page. It is $5 for 1,000 with no minimum, credits that never expire, and no charge for unknowns or duplicates.
