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.
MailboxValidator
MailboxValidator checks email addresses and mailboxes to flag invalid addresses and help reduce email bounces. It is available on the web and through an API, with single-address results returned as JSON or XML. For lists, users can upload text or CSV files for bulk validation. Checks cover syntax, MX records, SMTP responses, greylisting, disposable and free-provider addresses, role addresses, suppression, DMARC, strict SPF, and website reachability. The company says it tests the connection through the SMTP server without sending a message to the recipient. Listed integrations include Zapier, Make, MailChimp, Mailgun, SendGrid, HubSpot, and others; API documentation links libraries for Node.js, Ruby, PHP, Perl, Python, Java,.NET, Go, and Rust. The free API plan is free, billed per month, with 300 queries and 30-day validity. A bulk trial is free for 100 queries and 30-day validity. Yahoo validations are unsupported, and non-ASCII addresses are marked invalid syntax. The FAQ says refunds are not offered; its privacy policy says processed personal data is retained indefinitely, subject to policy limits on deletion requests.
