How Servyona verifies email addresses
See how Servyona checks email syntax, domains, MX records and SMTP signals before you send campaigns.
2. Syntax validation
We identify addresses with clearly invalid formatting.
3. Domain and MX checks
Servyona checks domain availability and available mail-exchange records.
4. SMTP signals
Where supported, SMTP checks help assess whether a mailbox may accept messages. Some servers restrict these checks.
5. Nuanced results
Results distinguish valid, invalid and uncertain addresses. Uncertain does not automatically mean invalid.

Servyona: an email verification engine tested at scale. Developed and optimized through internal test campaigns, including one involving 16,707 addresses, Servyona combines in-depth technical checks, multiple SMTP attempts and adaptive handling of mail servers. It identifies valid addresses, detects invalid ones and distinguishes uncertain results to help you clean your lists. These internal tests demonstrate processing capability and do not constitute an independent accuracy certification.
