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.
