Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZeroBounce is an email verification and deliverability platform for businesses, marketers, developers, and agencies. It validates individual addresses and uploaded TXT, XLS, XLSX, or CSV lists, while its real-time API supports programmatic checks. The product also covers disposable email detection, spam-trap and abuse-address detection, email scoring, Email Finder, inbox placement and server testing, blacklist monitoring, and DMARC monitoring. Access is available through web, iOS, API, and a Chrome extension.
Pricing covers free, one-time, and subscription options. The Free plan includes 100 validation credits per month, 1 inbox test, 1 email server test, 1 blacklist monitor, and 10 Email Finder queries; eligibility requires a business or premium domain. Pay-As-You-Go starts at $39 one-time for 2,000 email validation credits, with volume-based credit pricing. ZeroBounce ONE Monthly costs $99 per month for 10,000 validation/scoring credits, unused credits rolling over while subscribed, plus email deliverability tools. ZeroBounce ONE Annual costs $79 per month when billed annually, includes 10,000 validations per month, and provides a 20% discount.
Platform fit is a major strength for teams working across marketing, commerce, CRM, and development workflows. Integrations include HubSpot, Salesforce, Shopify, Mailchimp, MailerLite, WordPress, WooCommerce, Zapier, Google Chrome, and Mozilla Firefox. Custom allowlists and blocklists add control for recurring validation processes, while bulk uploads and API options support different operating models. Choose ZeroBounce when you need validation alongside monitoring, testing, scoring, and email-finding tools. Teams seeking only a straightforward address-checking service may find the wider feature set unnecessary.
