In their own words
Email Verifier API
Email Verifier API checks email addresses in real time to help reduce bounces and protect sender reputation. Its verification engine runs 16 checks, including syntax, SMTP, MX and DNS validation, spam trap detection, disposable and role account checks, and catch-all detection. Users can also upload CSV spreadsheets to clean lists.
The REST API accepts GET or POST requests and returns JSON by default, with XML available using an xml parameter. Each check uses one credit, but only definitive Passed and Failed results are billed; unknown catch-all results are not charged. The browser tool allows five daily checks without an account, and a new account receives 100 free credits without a credit card. Purchased credits do not expire, and the pricing page says purchases do not renew automatically. One-time packs include 1,000 credits for $9.95, paid once and 1,000,000 credits for $2,499.95, paid once. The service lists guides for C#, Go, Java, Node.js, PHP, Python, Ruby and Swift, and says submitted email addresses are purged after checking.
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.
