Bottom line
Email validation and scoring. Free 100 credits; ZeroBounce ONE starts at $99/mo for 10,000 validations.
Stands out for: Validation plus quality scoring on one meter, with a real free 100-credit allowance and a public $99/month subscription.
Watch out for: Pay-as-you-go starts at $39 for 2,000 validations if you do not want a subscription. Heavy lists will burn the 10,000-credit ONE cap.
Overview
ZeroBounce validates email addresses and scores quality so outbound recruiting and sales lists are sendable. A freemium plan includes 100 validation credits. Pay-as-you-go packs start at $39 for 2,000 validations. ZeroBounce ONE is the monthly subscription. MCP and an API are available.
ONE is $99/month for 10,000 validations and scoring. That is the cheapest paid subscription; the cheapest paid purchase overall is the $39 pay-as-you-go pack. Integrations include Zapier, Gmail, and Stripe. It is a verifier, not a sequencer and not an ATS.

Best for
