What Mailbeam is
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. The HTTP API requires no installed SDK, and integration examples are provided for Node.js, Python, PHP, Ruby, and Go. Mailbeam says cached and DNS-only lookups resolve in roughly 80ms from EU regions, while a full SMTP probe stays under one second. Its servers, databases, and processing are stated to run within the EU, using data centers in Germany. Real-time verification addresses are discarded immediately; batch lists and results are kept for 72 hours before automatic deletion. The Free plan includes 1,000 verifications per month; paid plans start at €19/mo, and the pricing note lists a 14-day trial. Monthly quotas do not roll over, and Free requests beyond the limit return a 429 error.
