In their own words
ZeroBounce
ZeroBounce verifies email addresses, cleans lists, and provides tools for sender reputation and inbox health. Validation is offered for bulk files and through a real-time API; the company claims 99.6% accuracy. Deliverability features include email warmup, inbox placement and server testing, blacklist and DMARC monitoring, and a dashboard. AI Email Scoring ranks addresses from 1 to 10, while Email Finder looks for professional addresses using a name and company domain. ZeroBounce lists more than 40 integrations and also supports API, SDK, and Zapier connections. An iOS app is available for list cleaning. The company says uploaded files are encrypted after TLS upload and deleted within 30 days, and that it operates its own data center and hardware rather than storing customer data on public cloud providers. A business account gets 100 free verifications per month. Pay-As-You-Go costs $39, paid once for 2,000 validations; ZeroBounce ONE costs $99 a month.
