We built the email verification API we wished existed
Mailbeam is built by Sopa Lab, a software studio based in Spain. We build developer-first infrastructure tools for European teams.
We kept running into the same problem when building products: existing email verification services were either slow, overpriced, non-compliant, or built by US companies that treated GDPR as a checkbox.
We built Mailbeam because European developers deserve a fast, honest, GDPR-first email verification API — built by a team that operates under the same regulations they do.
All infrastructure runs within the EU. Email addresses you verify are never stored after the request completes. Pricing is per verification with no tricks. That is the product we wanted to use.
Mission
Give every developer — from solo founders to enterprise teams — access to the most accurate, fastest, and most trustworthy email verification infrastructure in Europe.
How we work
Honest pricing
No credit multipliers, no hidden per-feature charges. You pay per verification and we tell you exactly what each check does.
Privacy by default
We built EU data residency and no-retention defaults from day one — not as an enterprise add-on. Your users' data is not our business.
Developer experience first
Every API, SDK, and error message is designed to make integration fast. If something is confusing, that is a bug on our side.
Transparency
When we don't know something — like a catch-all server's individual mailboxes — we say 'unknown', not 'pass'. Honest results build trust.
