ZeroBounce does email validation and deliverability: bulk list cleaning, an API and inbox placement testing. The free tier gives 100 validation credits a month, pay as you go starts at $39 for 2,000 validations, and the ZeroBounce ONE subscription starts at $99/mo. If you want lower pay-as-you-go pricing, credits that never expire, or verification bundled with an email finder or CRM enrichment, these are the alternatives we track. ZeroBounce publishes its pricing (Free 100 validation credits/mo; pay as you go from $39 for 2,000 validations; ZeroBounce ONE subscription from $99/mo), so the usual reason to look around is fit: a different feature focus, CRM, or price point.
