In their own words
Mailbeam
Mailbeam is a real-time email verification API for developers adding address checks to signup flows. It runs eight checks, covering syntax, MX records, SMTP existence, disposable and role-based addresses, free providers, catch-all detection, and explainable scoring. Results include a quality score from 0 to 100 and a machine-readable reason. Its HTTP API does not require an installed SDK, and examples are provided for Node.js, Python, PHP, Ruby, and Go. Mailbeam says cached and DNS-only lookups take roughly 80ms from EU regions, while a full SMTP probe stays under one second. Its servers, databases, and processing are in the EU, with data centers in Germany. Real-time addresses are discarded immediately; batch lists and results are deleted after 72 hours. The Free plan includes 1,000 verifications per month; paid plans start at €19/mo, and a 14-day trial is listed. Monthly quotas do not roll over, and requests beyond the Free quota return a 429 error. Mailbeam is built by Spain-based software studio Sopa Lab for European developers and teams.
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.
